The Dimensions of Colour, traditional colour wheel. THE RYB HUE CIRCLE OR ARTISTS COLOUR WHEELThe RYB hue circle or artists colour wheel is a hue system structured around the three historical primary colours, red, yellow and blue, and the historical complementary relationships red green, yellow violetpurple, and blue orange. This hue system, though founded on a scientific understanding of colour that was comprehensively overturned in the second half of the 1. Last weekend I was on Sewing Quarter, using fun shapes and tools to create two small quilts one of which used a bit of artistic licence The first is this Braid.

For details of these publications see Kuehni and Schwarz 2. After Newton introduced the circular dimension of hue in his Opticks of 1. This step was first taken in an anonymous chapter on pastel painting added to the 1. Hague edition of the anonymous Traite de la Peinture en Mignature, in a pair of hand coloured circles showing seven and twelve equal sized divisions respectively Fig. A, B. In the text the anonymous author hesitates over whether there are really three primitive colours or four yellow, blue and two reds fire red or vermilion, and crimson, but interestingly the primary status of red ultimately survives the fact that it had to be mixed here from two pigments. The seven hue circle shows the four pure pigments, plus three mixtures respectively of yellow, blue and the reds, while the twelve hue version adds further mixtures, to place yellow, the mixed primary red and blue evenly spaced around the circle. In both diagrams the clockwise sequence of hues follows the order of the seventeenth century linear scale yellow red blue, and so is reversed compared to Newtons spectral order red yellow blue. This twelve hue circle is the earliest example of the so called artists colour wheel, an arrangement of regularly spaced hue divisions structured around the three historical primaries. While it incorporated Newtons discovery that hues form a closed loop, the artists colour wheel was otherwise an implicit rejection of the assumption that Newtons circle and rules of additive mixing in which all spectral hues are primary also applied to paints. Despite this early example, published circular systems are few in number until the first decades of the nineteenth century, and in this early period triangular systems such as those of Mayer 1. Sowerby 1. 80. 9 are just as prominent. These triangular systems also arrange hues in a closed loop, but designate colours by the proportions of their yellow, red, and blue components, rather than by hue as such. Nineteenth century colour wheels are very diverse geometrically, and incorporate variously subdivided triangles, hexagons, and 6 to 2. Figs 7. 2. 2, 7. 2. Several of the systems shown here follow Moses Harris c. Field 1. 81. 7. These low chroma yellows, reds and blues were respectively known as olive, brown and slate following Harris or citrine, russet and olive following Field. This use of the word tertiary persists today alongside an entirely different usage, which can be traced back at least to Ruskin 1. In the context of the assumptions of traditional colour theory, tertiary colours of the first kind contain all three historical primaries, while those of the second kind contain two primaries in unequal proportions. When our anonymous author of 1. As in our naming of the historical primaries, the unconscious influence of the psychological primaries can be seen in our choice, out of the continuous sequence of hues obtained by mixing yellow and blue paint, of the simple name green for the colour automaticallyplaced opposite red. In the 1. 70. 8 text, no significance whatsoever was attached to pairs of opposing colours, beyond a general recommendation that colours distant on the circle should not be mixed. However when Harris published his colour circles in c. This assumption of the all purpose nature of complementary pairs remains typical of simplistic traditional colour theory today. During the late nineteenth century revolution in our understanding of colour, it progressively became evident that several fundamentally different kinds of opposing relationships exist among hues, including opponent relationships Section 7. Section 7. 4, and colourant mixing complements Section 7. In reality we need somewhat different hue circles to represent each set of relationships accurately. Which one we use depends on what kind of question is being asked. After this revolution, authors who continued to use the historical primaries mostly felt obliged to justify their position, given that the red, green and blueviolet primaries of Helmholtz and Maxwell were now widely regarded as the true primary colours by scientists. Their standard argument ever since has been that artists must work with pigments, and therefore their colour classification must be constructed in terms of the mixing of pigments rather than light. This argument neglects three crucial points 1. Artists may also be said to work with the light reflected by their artworks, and when the question concerns this visual stimulus as in simultaneous contrast, the appropriate framework is one based on light mixture. Most fundamentally, artists work with the perceptions of their audience, and hue perceptions are structured around the four psychological primaries. The clarification of the theoretical basis of subtractive mixing had revealed that the optimal primaries for colourant mixing were not in fact yellow, red and blue, but yellow, magenta and cyan, the complements of the additive primaries. What colour are yellow, red and blue The artists colour wheel can now be seen as an unconscious compromise, developed on the assumption that only a single hue circle was needed, at a time when the different kinds of opposite or complementary relationships were not understood. While they are unanimous in designating the primary colours as yellow, red and blue, such diagrams show far less unanimity in the paint or ink colours used to illustrate these primaries e. Figs 7. 2. 2, 7. 2. This variation reflects the nature of the historical primaries as a conflation of the four psychological primaries yellow Y, red R, blue B and green G and the three subtractive primaries, yellow Y, magenta BR and cyan GB, additionally complicated by the relative chroma of the available pigments. Thus, nineteenth century primary reds range from the the bluish red pigments closest to the ideal subtractive magenta primary insect, madder or alizarin crimsons, all around Munsell 2. R through psychologically middle reds around 5. R to the highest chroma available red vermilion, around 7. R. Nineteenth century primary blues range from the best available subtractive primary Prussian blue, around 7. B 1. 0B and psychologically middle blue around 1. B to the highest chroma available blue ultramarine, around 5. PB. Nineteenth century primary yellows span the range of the then available high chroma yellow colourants roughly 7.
