In color science, a color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. When this model is associated with a precise description of how the components are to be interpreted (viewing conditions, etc.), taking account of visual ...
Physical descriptions of color can be additive (describes mixing of light, RGB) or subtractive (describes mixing of pigment or removal of light, CMYK). Descriptions based on human perception are based on some experimental results on humans. Some models and their variants are employed in parts of the color spaces listed below. [1]
It is likely that the CPK colours were inspired by models in the nineteenth century. In 1865, August Wilhelm von Hofmann, in a talk at the Royal Institution in London, was using models made from croquet balls to illustrate valence, so he used the coloured balls available to him. (At the time, croquet was the most popular sport in England, so ...

A uniform color space (UCS) is a color model that seeks to make the color-making attributes perceptually uniform, i.e. identical spatial distance between two colors equals identical amount of perceived color difference. A CAM under a fixed viewing condition results in a UCS; a UCS with a modeling of variable viewing conditions results in a CAM.
The Natural Colour System (NCS) is a proprietary perceptual color model. It is based on the color opponency hypothesis of color vision, first proposed by German physiologist Ewald Hering. [1] The current version of the NCS was developed by the Swedish Colour Centre Foundation, from 1964 onwards.
The original CIECAM97s color appearance model uses the Bradford transformation matrix (M BFD) (as does the LLAB color appearance model). [3] This is a “spectrally sharpened” transformation matrix (i.e. the L and M cone response curves are narrower and more distinct from each other).
