About color

Color is produced by a computer monitor and printing device using two different color models (methods for displaying and measuring color). The human eye perceives color according to the wavelength of the light it receives. Light containing the full color spectrum is perceived as white; in the absence of light, the eye perceives black.

The gamut of a color model is the range of colors that can be displayed or printed. The largest color gamut is that viewed in nature; all other color gamuts produce a subset of nature's color gamut. The two most common color models are red, green, and blue (RGB), the method by which monitors display color; and cyan, magenta, yellow, and black (CMYK), the method by which images are printed using four process ink colors.
