Any hue that, in theory, cannot be created by a mixture of any other hues. Varying combinations of the primary hues can be used to create all the other hues of the spectrum. In pigment, the primaries are red, yellow, and blue.<br><br>Red, yellow, and blue, the mixture of which will yield all other colors in the spectrum but which themselves cannot be produced through a mixture of other colors.<br><br>The colors yellow, red (magenta), and blue (cyan) from which it is possible to mix all the other colors of the spectrum; also known as the subtractive or colorant primaries. Thus pigments that reflect light of one of these wavelengths and absorb other wavelengths may be mixed to produce all colors. Also, the light (-source) primaries: Lights of red, green, and blue wavelengths may be mixed to produce all colors. Light primaries are used in theatrical stage lighting, and in color video and computer screens.
