what are the primary pigment colors
For other uses, see Primary Colors. The emission spectra of the three phosphors that define the additive primary colors of a CRT color video display. Unlike subtractive systems that use magenta, yellow, and cyan inks, additive systems such as computer displays mix red, green, and blue light to make all colors.or human applications, three primary colors are typically used, since human color vision is usually trichromatic. For additive combination of colors, as in overlapping projected lights or in electronic visual displays, the primary colors normally used are red, green, and blue.
