The Martian Colour Wheel. The Martian 2. 4 Hue Colour Wheel click for full resolutionWhy do we need another colour wheel There have been numerous colour wheels over the ages, from Isaac Newtons in 1. Goethes in 1. 81. Wilhelm Betzolds in 1. Traditional, Printers CYMK and Physicists RGB wheels. Surely this ought to be enough you say. Its all been done you say. Colour has been well known for thousands of years you say. Well yes and no. For a start The traditional colour wheel is wrong. Wheel Of Colour' title='Wheel Of Colour' />Just ask any physicist or qualified printer. Just because there are legions of oil painters and water colourists the world over prepared to swear blue that the traditional wheel is the only true wheel, does NOT make them right. Secondly There are not enough hues in most wheels. Neither is satisfactory. Thirdly Most wheels only give the primary shade of that hue, no darker shades and no lighter tints. Fourthly The names of most of the colours are either missing, incorrect or so clumsy as be useless. The Martian Colour Wheel is based on the HSV cylinder but it uses 2. Abney Effect. It also keeps the full brightness of all the hue exemplars in order to match the richness of colour available on our RGB screens. There are also 2 dark shades for each hue and two light tints. The result is 1. 20 colours that cover most the gamut available on a computer screen and most colours that you can see in the real world. Obviously, since there are an infinity of colours in any given gamut you cant cover ALL of them with 1. WILL be a colour on the Martian Wheel that is close to any colour you can find on a computer screen. There ARE a few exceptions, namely very dark shades and mid to dark very unsaturated colours. I judge these to be less important than the brighter, more saturated colours and so, for the time being I have left them out. The Martian Colour Wheel also NAMES every colour with a simple, recognisable, real world example You may think that this is no big deal, but I assure you It is With the Martian Colour Wheel you have a vocabulary of colour that will cover almost everything you can see. Wheel Of Colour' title='Wheel Of Colour' />It will give you a way to talk accurately about colour that you have never had before. It will also give you a richness of understanding about colour that you never had as you learn to name colours accurately for the first time. The Martian Colour Wheel is an essential part of the education of all people with colour vision. It should be on the walls of all primary schools the world over Make it so What is colourMost painters think that they understand colour. They dont. They understand how to get the colour that they want on their canvas, or at least, something that will do. Most painters are labouring under the delusion that the 3 primary colours are Red, Yellow Blue. This incorrect notion goes back hundreds of years and its basis is the fact that at the time, with the pigments available, those 3 colours could not be made by mixing other colours. THE RYB HUE CIRCLE OR ARTISTS COLOUR WHEEL The RYB hue circle or artists colour wheel is a hue system structured around the three historical primary colours. They could not be mixed, therefore they had to be elemental. This is quite wrong as any modern printer knows, and who, using todays pigments, can mix up Red from Magenta and Yellow, and Blue from Magenta and Cyan. Yellow is the only one of the traditional primaries that cannot be mixed with paint. Printers may think that they understand colour and unlike most painters, they at least do have a real set of 3 primaries in Yellow, Cyan Magenta that do more or less follow a sound theory.

A colour wheel of equally spaced 24 hues and 5 tones each giving a representative colour vocabulary of 120 mostly saturated colours. Each colour is named after an. Wheel Of Colour' title='Wheel Of Colour' />This is only because chemists have finally found some high intensity, transparent pigments that mix cleanly namely Pthalo Cyan, Quinacridone Magenta and Arylide Yellow. These nice modern synthetic pigments make the subtractive theory of colour appear to work. However as any painter knows, as soon as you use normal opaque pigments it falls down. Physicists think that they understand colour with their additive primaries of Red, Green, Blue and they have computer screens and cameras to prove itYes, it is they that understand best, with their additive system of colour that deals with pure light. However the system breaks down when used with paints, although it does work partially, thereby dispelling the idea that the subtractive theory has all the answers when it comes to paint. The reality is that Colour is an extremely complex subject which cannot be explained by any simple theory. It is a tricky business because of the following It is a subjective experience that exists only in the mind. The human eye is stimulated by 3 colour sensors and the mind interprets that data. What you see is just an interpretation of the data, not the data itself. Light in the real world is not composed of mixtures of three primaries but selections from an infinity of wavelengths through the visible spectrum and beyond. Konashion Game. Such selections are never composed of a single spectral hue but 5, 1. This is quantum mechanics that you can see The colour of a nice pink rose that you see many be composed of 2. Real world hues are spectral hues, that is, they exist ONLY along the rainbow line from Red to Blue. None of the hues of purple and pink actually exist on the spectrum. Hues that are composed of a mix or Red and Blue exist only in the human mind, where the RGB colour wheel is part of the eyes interpretation algorithm. There is no Pink or Purple wavelength. The only reason you see Violet in the visible spectrum is due to a secondary peak in the red sensor sensitivity spectrum past blue. The brain interprets this second red peak the same as it would the primary red peak and assigns this weak blue along the purple line. In fact, it belongs in the blue. The term Ultra Violet is a misnomer as there is no Violet in the real world, only in the imagination. It should be termed Ultra Blue. Surfaces in the real world do behave purely as absorbers or transmitters but mixtures of the two so that in most cases neither the additive nor the subtractive theory of colour work properly. There are exceptions such as computer screens and transparent clean mixing dyes in colourless medium, but these are highly artificial, the real world is difficult. Whats so special about colour namesWeve already got lots of colour names I hear you cry. Weve got red, blue, yellow, green, violet, teal, pink, fuchsia etc. Well yes, thats true but when you look closely at them you find that they are not as helpful as you think. Thanks to Physicists and Printers we have a good agreement on the precise meaning of Red, Blue, Green, Yellow, Cyan and Magenta, although even here there are problems Is Green the full intensity of green pixel or somewhat less Cyan and Magenta have predecessors from the art world of differing hues. Nevertheless, the precise definition of the 6 primaries is pretty well fixed. The same, alas, cannot be said for the names of all the rest of the colours Take Pink for example. It is used to describe anything from Purple to Red and in differing shades and tints. The same imprecision is also apparent for Purple. We all agree on what true Blue is but there are a vast array of hues, tints and shades that are referred to as Blue yet are nothing of the sort including Sky Blue, Sea Blue, Baby Blue etc. The same kind of mess is also apparent with Green where there is a lack of distinction between Green, Emerald and Cyan.
