Each color receptor respond to different ranges of the color spectrum. However, the human eye normally contains only three types of color receptors, called cone cells. For humans, three primary colors are usually used, since human color vision is trichromatic.įundamentally, light is a continuous spectrum of the wavelengths that can be detected by the human eye, an infinite-dimensional stimulus space. Primary colors are not a fundamental property of light but are related to the physiological response of the eye to light (the way the eye works). įor additive combination of colors, as in overlapping projected lights or in television and computer screens, the primary colors normally used are red, green, and blue.īiological basis Other sets include the RYB system of red, yellow, blue, especially used by artists.
