Representing color by three numbers, whether physical values, such as the colors of a computer display, or perceptual values, such as the CIE tristimulus values, is fundamental to the science and industry of color. It is used implicitly in computer graphics, where color is most often defined as triples of red, green and blue values. This tutorial explores trichromatic representations in the context of graphics, and presents a quantitative mechanism for tying RGB triples to physical and perceptual values.
