Trichromatic Theory

A theory of color vision that suggests our ability to perceive color is based on the response rates of three types of cones in the eye, each sensitive to different light wavelengths.

Color Vision

The capability of the visual system to distinguish objects based on the wavelengths of the light they reflect, emit, or transmit.
