# Colour Sequence Application to Continuous Line Drawings by Mick Burton – demonstration continued.

Clyde the Elephant, single continuous line with colour sequence by Mick Burton.

This is the continuation post covering my demonstration and workshop at Harrogate and Nidderdale Art Club on 6 December 2018.

Here is a reminder of my marker pen attempt at a continuous line elephant.

Demonstration of a Single Continuous Line Elephant, initial drawing, at Harrogate and Nidderdale Art Club by Mick Burton, on 6 December 2018.

At home later I followed the line/s around and found that there was more than one line and I needed to do one or two diversions to correct that.  As the pattern at the front of the neck has a sort of square which I needed to get rid of I used that region to also turn the drawing into a single line throughout.  With a bit of general smoothing of arcs all round I arrived at the following revised elephant.

Revised single continuous line elephant.    Mick Burton, Leeds Artist.

The next stage was to apply my Colour Sequence to the lines, which I completed in the last few days.  The result is shown at the top of this post.

To explain the process I use, and how it works, I will briefly go through the illustrations which I used later on in the Demonstration at Harrogate and Nidderdale Art Club.

We start by drawing a winding line in an anticlockwise direction.

Stage 1. Single line drawn anticlockwise.   Mick Burton explains colour sequence.

Then, starting on an outside section of line, overdraw in red alternate sections of line.  This results in three different continuous line sections bounded by a red line.

Stage 2. Overdraw in red missing alternate sections.   Mick Burton explains colour sequence.

We can now number all the areas to indicate where the colours in the sequence go.  Call the outside 0 and number through the sections to 5 in the middle.  You will see that each channel between red lines has alternately numbered areas.

Stage 3. Number the areas in sequence from the outside (being 0) to the middle (being 5). Mick Burton explains colour sequence.

I have already decided on a sequence of colours to use, running from light tones to darker and from yellow to red.  First apply yellow and gold alternately throughout the outer corridor.

Stage 4. Paint alternate colours within the outer corridor. Mick Burton explains Colour Sequence.

Paint in the next two colours from the sequence – orange (which looks reddish here) and red – alternately in the inner corridor.  You can see how the colours are lining up in natural sequence of tone and colour.

Stage 5. Paint second set of alternate colours (orange, which looks reddish here, and red) in the next corridor.   Mick Burton explains colour sequence.

Lastly, for our anticlockwise line we paint the central area (which has its own red line surrounding it).  The result is a simple set of sequences running from the outside to the middle.

Stage 6. The last colour in the sequence (dark red) is added in the centre. Mick Burton explains colour sequence.

As you will have realised, each loop going over earlier parts of the drawing adds a level, like overlapping shadows or leaves on a tree looking darker as they overlap.  The direction of darker tones of colour in the sequence reflects this.

In more complex drawings, however, the sequences of colours can change direction.  To show this we need to have a different single continuous line.

Start drawing your line with two loops from the lower left in an anticlockwise direction as before.  When you reach the upper left change to doing three loops in a clockwise direction and then go back to the start by a line running underneath.

Stage 7. Start drawing your line from the lower left in an anticlockwise direction doing loops and when you reach the higher left change to clockwise loops running back to the right. Then finish clockwise running underneath to the start. Mick Burton explains colour sequence.

Here is confirmation of the directions of the line, anticlockwise and clockwise, and how they change and run back over earlier lines.  We now have a more complex drawing for colouring.

Stage 8. Here is the completed single line with the directions shown – red for anticlockwise and blue for clockwise. Mick Burton explains colour sequence.

By applying alternate overdraw in red we split the drawing into corridors which look a bit more complicated than the simple anticlockwise drawing we did earlier.

Stage 9. Alternate overdraw in red splits the new drawing up into corridors for colouring. Mick Burton explains colour sequence.

When we number the areas, starting at 0 on the outside as before, we have plus numbers at the top of the drawing but minus numbers appear in the lower corridor.  When we follow the natural sequence of numbers downwards from 2 through 1 and 0 we hit -1 and -2.

Stage 10. Numbering from 0 on the outside as before we get minus numbers as well as plus. Mick Burton explains colour sequence.

After I had been doing my colour sequence for a few years I found out that mathematicians call this mix of anti and clock directions Winding Number Theory.  When you continue with loops in an anticlockwise direction you are adding levels of overlap and when you change to clockwise you start reducing levels.

We can now apply alternate colours yellow and red to the upper channel.

Stage 11. First set of alternate colours in the upper channel on the complex drawing. Mick Burton explains colour sequence.

Then we can complete the positive colour direction.

Stage 12.  Completing the plus direction colours by adding dark red.   Mick Burton, continuous line artist.

Now looking at the lower colours, in the clockwise section of the drawing we add the final two colours alternately.

Stage 13.  Complete colour sequence on single continuous line drawn in both anticlockwise and clockwise directions. Mick Burton, Leeds artist.

So that is the basis of how I do my colour sequence.

For my elephant, it is more complicated and I show below my sketch after doing the alternate overdraws to create the corridors of alternate colours and then numbered the colours throughout.

Single continuous line elephant showing alternate overdrawn lines in red and colour numbering. The key to the colour sequence and numbering is shown. Mick Burton, continuous line artist.

I have shown the key to the colour sequence and numbering in the top right corner.  The colours can be employed in the opposite direction, of course, but with all my drawings the choice of which direction of sequence to adopt is not too difficult.  The darker colours fall lower down or on the main body of the animal and the more delicate red, orange and yellow mostly on the face.

I only use red once, and that is on the eye.  This really reflects the greater detail on a face which extends the colour range.  Several of my colour sequence animals have the eye coloured by an end of range colour only used once in the drawing, eg. Iguana, Harriet the Hen and Olympic Lion.

The completed elephant, at the top of the post, has a story behind it.  I did the initial drawing in my demonstration to Harrogate and Nidderdale Art Club on 6 December 2018, which is the day my first grandson, Lucas, was born in Glasgow, son of Kate and Mark.

I have decided to call the elephant Clyde after the famous Glasgow river.  Lucas can have a picture on his wall which is exactly as old as he is.

# Demonstration and Workshop at Harrogate and Nidderdale Art Club by Mick Burton, Continuous Line Artist

Mick Burton explains how alternate shading can be used to colour a completed single continuous line.  This is Dottie, a lurcher pointer cross.   Harrogate and Nidderdale Art Club, December 2018.  Photo by Chris Noble.

As a member of Harrogate and Nidderdale Art Club I was delighted to run a workshop in December 2018 to demonstrate how I do my Single Continuous Lines and here I explain (above) how black and white alternate shading was applied to Dottie at the request of her owners.

Here is a photo of Dottie (below) checking out her portrait.

This is Dottie checking out her portrait, done in Single Continuous Line with alternate shading by Mick Burton.  Photo by Stuart Firth.

I explained what my approach was to drawing Single Continuous Lines.  People often assume that I start at one point and draw the line, depicting my subject, all in one go and finish where I started.  I have done this from time to time, and my cat drawing is an example, but I now complete all my drawings in sections and then gradually connect up all the loose ends.

One of the more enjoyable parts of doing continuous lines is the freedom to incorporate all sorts of patterns involving curves, loops, sharp corners, etc.  In my case doodling these patterns was first triggered when I saw examples of Art Nouveau when I was about 9 years old.   I now drew some examples for the members and asked them to have a practice.

I then explained my approach to drawing an animal.  After doing a very basic sketch of my subject, I put in key marks throughout and then start on one section, such as the head.  Next I will initiate other parts such as legs and other distinctive features before connecting up all the lines.  I do not worry at this stage if there is more than one continuous line throughout, or that the lines may appear to be crudely drawn.

I said that I would demonstrate this approach by drawing an elephant, a subject which I have not attempted for about 50 years.

The result is shown below.  At home I usually start by using pencil on A4 size paper so that I can change the line as I go on.  The result can be scanned into my computer so that I can scale up to any size using Excel.  For Dottie, above, scaling up resulted in printing off 10 A4 sheets to stick together so that I could then trace through onto a big canvas.

For demonstrations I use a thick marker pen, usually on to A2 size paper but as there is a large screen at this club I used A3 size paper.  Poor quality paper is alright as the marker moves more smoothly, but of course a slightly shaking hand is magnified on the big screen.

It is important to keep an eye on loose ends.  I realised that I had three at one stage and was struggling to see the fourth, but a member spotted it on the big screen.  It was not too far away and I could link it back in without making the lines look too congested.

I said that this was fine as an example and the members could now have a go at any subject they wanted.  Also not to worry too much about loose ends or not being able to keep the lines clean.  Part of my aim was to introduce elements that could be incorporated into their own work and to encourage people to develop patterns or techniques of their own.

Regarding my elephant, I said that I would smarten it up later at home, by making sure that there was only one continuous line, smooth out the curves, etc and show them the result at a later meeting.  Also, I would produce a coloured version at home to link in with my intention to explain my colours later in the current session.

I was pleased with the drawings the members produced and enjoyed going round discussing their progress.  Here are a few examples of their lines, continuous or otherwise, including some colouring (which I did not start to cover until after these drawings).

Whilst members were continuing with their continuous line drawings I talked about the backgrounds that I had gradually introduced into my pictures to add to the overall composition including my continuous lines.

Rather than simply have a plain background I have added to many paintings a simple coloured pattern effect which I feel complements the individual composition.  One example is a layered graduation of colours for my Single Continuous Line of a pig with my colour sequence.  I call the picture “Pig with Rasher Sky”.

Another background is in my “Stained Glass Window Horse” which appears below.  Having spent considerable time in Ripon Cathedral when young I was always impressed by stained glass windows.  I also read a lot of Dandy comics where Desperate Dan sometimes jumped through a brick wall, “into the middle of next week”.  Consequently the horse has a gap in the wall similar to its outline and I have not included any cement and so that the sun shines through the gaps in the stones as well as the glass.  I chose a canvas where the sun can shine through as well.

Later in the session I explained how my colours are devised and applied and I will cover this in a further post soon, which will also include the finished version of my new elephant and how my colour sequence naturally applies to it (hopefully).

# Another Stainbeck Artist, single continuous line drawing.

Zena – Another Stainbeck Artist, single continuous line drawing portrait.  Mick Burton continuous line blog, 2018.

For this latest single continuous line drawing, I have used my gap technique to emphasise the crossovers of the lines and thickened certain key crossovers to try and further increase the three dimensional effect.

You can compare the result with the gaps only technique that I used with my blue horse in 2012.

You can also compare the portrait (above), based upon a 10 minute sketch of Zina done at Stainbeck Arts Club in late 2017, with my first single continuous line portrait (below) based upon a sketch of Barrie done at Stainbeck in 2012.

I have also used the combined gapping and selected thicker lines on the single continuous line drawing of the Iguana, originally created in 1971.  The colour sequence version of the Iguana being featured on my previous post in July 2018.

# Updated WordPress Galleries for continuous line artist Mick Burton

Iguana single continuous line drawing with colour sequence. Mick Burton, Leeds, Yorkshire, 1971.

At last I have got round to updating my galleries of both “New Work since 2012” and “Gallery 1965-74”.   Here one of the additions to my older ones – Iguana, which I did show in an early post in July 2014 but did not include in the Gallery.

I now have a fantastic gallery with a tiled format where every picture has been sized to fit and those in short related sequences seem to be logically placed as well.  Exactly what I needed and way beyond what I expected.

Do have a look.  You can click on any picture to see it in detail and then click on arrows to see the whole gallery in turn.

# Hot Cross Bunny and the psychology of colour

“Hot Cross Bunny”, single continuous line drawing painted in psychological colours. Mick Burton, continuous line artist.

In my posts I have said a lot about colour sequence and, along the way, talked about selecting appropriate ranges of colours for my drawings.  Here are some more colour comments, leading to the one about the bunny above.

I might consider that a yellow, red and brown range would be good for my horse. These have a similarity to its actual colours and give a warm and friendly feel which reflect the horse’s nature and temperament.

A strong harsh colour seemed to be best for my roaring lion and simple black and white achieved this.  In the mid 1960’s when I drew the lion, Bridget Riley had been doing many black and white hard edge pictures, and I did several of my animals in this colouring.  I feel that this worked best for the lion amongst my drawings.

With my “Flame on the Sun” painting, the sort of anti magnetism represented by complementary red and green hopefully reflect the explosive violence required.

For a more subtle result – my still life of a radish, apple, mushroom and flower heads – I used water colours to help to show the floppy translucent nature of the radish leaves.

Sometimes I find that I can use almost actual colours.  Here is a commission drawing, with the continuous line running through both robins and the branch.  I  was asked to do only a hint of pink on the Robins’ chests.  This is fine.  However, I had to have a go at a full colour result for myself.  The perky nature of robins is reflected pretty well, I think, by these “near” natural colours.

My yellow, green and blue sequence of colours fits well for “Nibbles”, a friendly rabbit who likes nothing more than eating her greens.

However, for a rabbit drawn with exactly the same single continuous line as for Nibbles, but who has a completely different temperament  –  RED, BLACK and WHITE fits the bill.

This is, of course, “Hot Cross Bunny” who lurks at the top of this post.  A real, full on, “Psycho”.

The two Rabbit paintings and the Pair of Robins accompanied several other of my pictures at the Harrogate and Nidderdale Art Club exhibition a week ago at Ripley Town Hall.

At the Preview Evening various prizes are awarded.  One was the annual prize presented at the Spring Exhibition by Sir Thomas Ingleby, the club’s patron, for his own personal choice for the best picture on show.  This was won by Julie Buckley for her “Black Labrador”.

Sir Thomas also mentioned other pictures which caught his eye.  He said that he liked all the paintings by Mick Burton, but never thought that he would ever consider buying one called “Hot Cross Bunny”.

Here is a bit of background to the Rabbit paintings.  Nibbles and Hot Cross Bunny are based upon my daughter Kate’s rabbits, Harriet and Clover.

Harriet was friendly and cuddly and Clover might have been better named “Cleaver”.  We kept them both in the garage – in separate cages.

When we bought Clover, a lop eared rabbit, the breeder was saying how friendly and harmless the baby rabbit was.  I asked if it was related to an adult lop eared which had just tried to bite my finger off and the answer was “Yes, it’s the granny”.  We still bought Clover!

She was alright at first but later became very aggressive.  Every time we opened her cage for any reason, she would bite viciously.  We also realised that some one else would have to take care of the rabbits when we were on holiday.

Strangely, I found that if I put a hand on Clover’s head as soon as I opened the door she would stay still and relaxed as long as I kept the hand there.  With the other hand I could top up food and water or clean out the cage.  This worked for all of us.  Fortunately, our neighbour was delighted to be able to do this too and things were fine when we were away.

After Clover died and I had buried her in the garden, Kate prepared a wooden plaque and nailed it to the fence “Here lies Clover Burton the rabbit”.

An interesting consequence of keeping the rabbits was that straw from the bale became piled on the floor of the garage.  One day the straw was seen to be moving and we feared that we had rats and so I was deputed to check it out.  I found a nest of baby hedgehogs.

# Kaleidoscopic Wild Horses, continuous line drawing with colour sequence.

Kaleidoscopic Wild Horses. Single Continuous Line Drawing with colour sequence in acrylic on canvas.  I happened to have a canvas 36″ x 10″ previously intended for an upright picture idea.  Mick Burton continuous line artist 2017.

This painting originated from a continuous line drawing which I produced for a demonstration at Stainbeck Arts Club, Chapel Allerton in Leeds in May 2017.

Wild Horses,  single continuous line drawing. Demonstration at Stainbeck Arts Club. Mick Burton, continuous line artist 2017.

When I was thinking about a subject for the demonstration I saw an advert on the TV for the Cheltenham Festival which just showed loads of horses running – why there were no riders or jumps I do not know.  This also reminded me of one of my favourite paintings – “Scotland Forever” by Lady Butler in Leeds Art Gallery, painted in 1881.  A bit like “Charge of the Light Brigade” but straight at you, with the horses wild eyed and seeming to leap out of the painting.

See it at   http://www.leedsartgallery.co.uk/gallery/listings/l0081.php

Lady Butler painted a lot of war scenes and of course she had no military experience.  She was, however, married to a General and she persuaded him to let her watch manoeuvres.  In preparation for this picture she asked that the cavalry ride straight towards her so that she could get the feel for facing a charge.

When I had finished the demonstration, which was a result considerably rougher than the above, the members asked about colours.  I had not intended to talk much about colours, as I thought that my approach to drawing the lines would be enough at this session, but we had a solid half hour talking about my method and ideas about colour.  They said that they looked forward to seeing the image in full colour, so here it is.

My original intention was to do a black and white alternate shading version only, and this is shown below.  The tweaking which I did on the horses heads to achieve a better result in black and white was essential both to improve the continuous line and later to enhance the colouring.

Wild Horses, single continuous line drawing with black and white alternate shading.  Mick Burton, continuous line artist 2017

Initially I did my normal approach to colour sequence, where I devised a 6 colour range (white, lemon, golden yellow, orange, vermilion red and crimson alizarin) to fit my alternate overdraw template for this image.

This resulted in gold and vermilion appearing on all outer areas and I thought that I needed a darker effect in the lower half of the image.  So I substituted cobalt blue for gold along the bottom legs of the horses and finished up also substituting, on an ad hoc basis, some dark blue, violet and green to try and naturally leach colour balance upwards to meet existing vermilion and gold.

A fellow artist who likes my alternate overdraw and colour sequence method has told me that I should always apply it fully to get the natural result.  Generally I would agree, but thought that I needed to break some rules on this occasion.  I try and mirror nature in my art and of course nature evolves by breaking a few rules.

Joan and I visited my Aunty Ann a couple of weeks ago.  She is 99 years old and still as bright as a bobbin.  She is a good artist and only gave up painting relatively recently, and always wants to see my latest stuff.  i took the Wild Horses along.  It took up the length of the settee and she was delighted with the colours.  I then realised that the painting’s reflection in the shiny metal fire surround made the composition even more abstract.

# Leeds Olympic Lion, a new single continuous line painting by Mick Burton.

Leeds Olympic Lion, coloured in many shades of red, white and blue to commemorate all the Leeds based athletes and swimmers who brought back medals from the Rio Olympics, 2016.  Mick Burton single continuous line drawing with colour sequence.

I did a demonstration at Farsley Art Group on 12 July 2016 and the continuous line drawing I used as an example was the basis for the above painting. The Group showed a lot of interest and produced many fine attempts at continuous line during my workshop. The club kindly featured me on their website, showing some of my drawings as well as work by members.  I gave them a free hand to put their own stamp on their continuous lines so we had some great variations.

Joan, my partner, watched many swimming and diving events on the TV during the Olympics broadcasts.  She worked at the Leeds International Pool and the new John Charles Centre, in various swimming organising roles, before she retired in 2012 and was delighted with the results of the Leeds members of the Great Britain team and their coaches.

As the athletes all had the red, white and blue lion on their track suits I felt I had to colour my Lion in a range of similar colours and call it the Leeds Olympic Lion.  The painting will be exhibited in the Stainbeck Arts Club Annual Exhibition on Saturday 3 September 2016.  The exhibition is part of the Chapel Allerton Arts Festival taking place in north Leeds this week.

Joan’s daughter, Helen Frank, represented Great Britain in the 100 metres breast stroke in the Seoul Olympics in 1988 and was one of five swimmers from Leeds.  Adrian Moorhouse won a swimming gold medal, in the 100 metres breastroke, in 1988.  A gold by a British swimmer was not achieved again by a  British swimmer until 2016.

Helen brought back a commemorative plate from Seoul, which is part of Joan’s collection of Olympic Plates.

This colour sequence squirrel is the last of a series which began with my attempt to produce a continuous line drawing with a shimmering fur effect for the squirrel.

I have a treasured memory of seeing a Red Squirrel, when I was four, sitting on a wall next to our cottage at Arncliffe Hall, in the North Riding, where my Dad was Head Gardener to Sir Hugh Bell just after the War.  I thought that completing alternate shading with copper paint would best reflect this colour in this picture from 1970.  My daughter Kate said on the phone today that she remembered this picture being in the hall when she was young.

Red Squirrel, single continuous line drawing with copper alternate shading from 1970. Mick Burton, Leeds continuous line artist.

I have many clear memories of living at Ingleby Arncliffe from the age of nearly two, to four and a half when we left.

Falling out of my pram outside the local shop and crawling up the step was the earliest. There was a three legged cat, then at Sunday School one of the stamps I collected was “The Light of the World” by William Holman Hunt (my first taste of the Pre-Raphaelites) and I won the child’s sprint on sports day on the cricket ground.

In the famous terrible winter of 1947, I remember Dad helping to dig a trench in the snow drifts down to the village.  It was amazing to walk along the trench and not be able to see out.

I once watched a pig being killed in the yard by the cottage and the workman laughed as he squirted me with the pig’s bladder.  This memory came back years later when, as a young police constable, I attended my first post mortem (of a coal miner who had been in an underground tunnel collapse).  My sergeant stood with me and assured me that it would be just like a newly killed pig being cut up, if I had ever seen one.  I said “Yes, I saw one when I was four ! “

I only see grey squirrels now, mainly helping themselves to the bird seed Joan puts out.  With Gledhow Valley Woods at the end of the garden we can have five of them at a time.  Yesterday, a young squirrel was chased by a cat and ended up on the trellis a few feet from our dining room window.  Joan chased the cat away and called to me as the squirrel was too scared to move.

I took some quick photographs whist it was still there, but it became apparent that it was not going to move and was looking at me pleadingly.  So I went out and shepherded it into the bushes.  Here are some photos of a shimmering fur tail.

# Four Colour Theorem continuous line overdraw.

Continuous lines overdrawn on Skydiver formation design, using Four Colour Theory method. Mick Burton

My recent post about the formation design used by the record breaking skydivers included a continuous line overdraw of their design (modified slightly be me to complete links which would have been present with more skydivers).  I said that I would explain how the overdraw (above) was completed.

The structure is made up of circles which have 3 way junctions throughout (3 handed in the case of skydivers ! ).  This can be regarded a map and so I will apply my Four Colour Theorem continuous line overdraw which I devised in the early 1970’s.

I was trying to prove the Four Colour Theorem, which states that no more than four colours are required to colour all the regions of a map.  My basic idea was that drawing a single continuous overdraw throughout a map would split it into two chains of alternate regions, which would demonstrate that only 4 colours were required.  If more than one continuous overdraw resulted then there were still only two types of chains of alternate regions.

As you will probably know, this theorem has many complexities which I will not attempt to cover here.  In the mid 1970’s I corresponded with two mathematicians at the Open University about my approach, Robin Wilson and Fred Holroyd, who were both very helpful and encouraging.  The theorem was proven in 1976 by Kenneth Appel and Wolfgang Haken, running one of the biggest computers for over 1000 hours.  I soon decided that it was time to go onto other things!  However, my journey had been fascinating with numerous amazing findings which have been so useful in my art.

I can keep to relatively simple methods for my pictures.

Here is the design, used above, with my initial overdraws shown in red.

Assumed formation design used by Skydivers, with initial overdraws. Mick Burton four colour overdraw.

On final completion of the overdraws, every junction should have two of its three legs overdrawn and so the start decision (1) above overdraws two legs and this means that the third leg, which I call a “spar”, links to another junction where the other two legs must be overdrawn.

We then carry on making decisions which trigger other overdrawn lines across spars.  Usually there is a “knock on” effect where new overdraws connect with already overdrawn lines which then trigger more overdraws.

If we go wrong and a junction is triggered which has all three legs overdrawn, or none, we have to go back and change earlier decisions in a controlled process.  I usually photocopy the overdraws completed, every two or three stages, so that going back is not too time consuming.

Here is the situation after decision (3).  Decision (2) in blue had only triggered two overdraw sections but decision (3), in green, has triggered ten sections to be overdrawn in green.

Four Colour Overdraw decision 3 triggers 10 further overdraws, in green. Mick Burton, continuous line artist.

Here is the completed overdraw.  It can be seen that some decisions still only trigger one or two overdraws, but decisions 5 and 7 triggered 13 and 12 overdraws respectively.  There are 80 junctions in the design and it took 11 decisions to complete the overdraws.

completed Four Colour Theorem overdraw, on design based upon Skydivers formation design. Mick Burton, continuous line artist.

The completed overdraw has several continuous overdraws.  I tried other variations but had to accept that this design cannot be overdrawn with a Single Continuous overdraw.  This is due to the design having basically only two full rings of circles, which means that some tips of petals cannot be included in a continuous overdraw.

This situation can be overcome by adding links between the tips of the petals to produce that extra ring of areas.  Here is the expanded design and the stages of overdraw.  I managed to complete the Single Continuous overdraw in one sequence without having to go back to change any decisions.

Of course it looks better with one solid colour overdraw and no decision numbers.

I have said that the method of overdraw was developed with Four Colours in mind, and so you could use one pair of colours alternately within the above overdraw and another pair of colours on the outside of the overdraw (which can include the background).

I have found another interesting result in that if you use strong colours inside the overdraw, as it is the main image, and neutral colours outside (or even leave the outside blank) then the gaps between the “petals” show good use of space.  Here is the design simply coloured in strong red inside the overdraw, which creates a good contrast as the background seeps in.

The chains of areas produced by the continuous overdraws can be coloured, not just in two pairs of colours to demonstrate Four Colours, but with a colour sequence or a mixture of sequence, alternate colours or even one colour.  In the last picture I have used colour sequence on main chains of areas related to the central space and, as a contrast,  light grey on the chains connected to the outside of the design.

This is one of the first paintings that I produced after discovering my Four Colour Theorem overdraw in 1971. I called the picture “Star Burst”, one of my first planetary pictures.

# Spherical Continuous Line Abstract with Colour Sequence.

I have modified my Spherical approach to continuous line from the method I described in my Continuous Line Blog post of 9 July 2014, which did not quite reflect the reality I was seeking.

I have kept the idea that when you draw out of one SIDE of the paper you need to return at the opposite SIDE at the corresponding point, so that the pattern matches vertically and after colour sequence the colours also match if you pull the paper round into a tube shape.  This is similar to the equator on a globe of the world matching.

Previously I had said that when going out of the top of the drawing you also need to return at the corresponding place at the bottom.  I was correct to say that the colours would not match, which would be equivalent to the poles on the globe of the world not meeting, but the treatment of the lines needed to be modified.

I realised that the bunching effect of the top being pulled together totally separately to the bottom being pulled together was fine regarding separate sets of colours but matching the line patterns from top to bottom was the wrong approach.

So, when I go out at the TOP now I need to come BACK IN AT THE TOP at the corresponding distance from the other end of the top.   Similarly if I go out at the bottom I come back in at the bottom.  You could then imagine that folding the picture vertically down the middle would mean that both pattern and colour sequence would now match at the top and bottom respectively (don’t actual fold it and spoil the picture ! ).

I recently drew the following for a demonstration/workshop at Stainbeck Arts Club in Leeds.  I started drawing the line a couple of inches in from the top left side and did a few rolling curves diagonally down from left to right, followed by several exits and returns to the picture – initially out at the lower right side and back in at the lower left side, then down and out at the bottom left and back in at the bottom right.

I later tried some “shark fin” curves and a couple of large jagged sequences.

All the time I tried to draw the line cleanly through existing shapes (avoiding going near previous junctions) and being aware of areas I had not visited much.  Finally I needed to work out how to get back to my start point without spoiling the composition too much (here going out and back in can be handy).

I hope you can check the route of the line through the whole picture fairly easily.  I then applied my Colour Sequence to produce the picture at the top of this post.

The first stage is my usual alternate overdraw of the line (if you are overdrawing a section as you go out of the picture you need to continue to overdraw as you re-enter, or if not overdrawing going out it’s not overdrawing when you re-enter).  See my post of 10 September 2014 for the full ALTERNATE OVERDRAW process and my post of 27 September 2014 for the COLOUR SEQUENCE process.

I have used a series of 6 colours from Pale Yellow through greens to Prussian Blue which I have tried to work out in steps of tone.  This is partly to highlight the overlap effect of continuous lines and the natural depth of the abstract.  As always, there is choice of direction of colours – light to dark or dark to light.  Here it seemed best to have the single lightest area at the top and several darker areas across the lower part of the picture.  The picture also has an Optical Art look about it.

Printing the picture in Monotone is usually a good way of checking the steps of colour and light to dark.  So here it is.

I also produced another similar abstract for the Demonstration at Stainbeck Arts Club to show the Spherical approach with a different flow of lines and colours.  I had coloured the drawing with a sequence from Yellow through Reds to dark Brown.
