10 Facts About Primary colors

Primary colors can be conceptual, either as additive mathematical elements of a color space or as irreducible phenomenological categories in domains such as psychology and philosophy.

The choice of primary colors has changed over time in different domains that study color.

Descriptions of primary colors come from areas including philosophy, art history, color order systems, and scientific work involving the physics of light and perception of color.

In physics, the three primary colors are typically red, green and blue, after the different types of photoreceptor pigments in the cone cells.

Exact Primary colors chosen for additive primaries are a compromise between the available technology and the need for large chromaticity gamut.

Over decades, market pressures for brighter Primary colors resulted in CRTs using primaries that deviated significantly from the original standard.

Course, the notion that all Primary colors can be mixed from RYB primaries is not true, just as it is not true in any system of real primaries.

Printers traditionally used inks of such Primary colors, known as "process blue" and "process red", before modern color science and the printing industry converged on the process Primary colors cyan and magenta.

The X, Y, Z and the L, M, S primaries are imaginary, since none can be represented by real lights or colorants, and complete since all colors can be defined in terms of primary intensity coefficients that are all nonnegative.

Francois d'Aguilon's notion of the five primary colors was influenced by Aristotle's idea of the chromatic colors being made of black and white.
