Trichromatic Theory

The idea that three types of cone receptor cells in the retina are responsible for color perception. Each type responds optimally to different, but overlapping, ranges of wavelengths.

L Cones

Photoreceptor cells in the retina that are sensitive to long wavelengths of light, contributing to color vision, particularly red colors.

M Cones

Photoreceptor cells in the retina specialized for medium-wavelength light, contributing to color vision and perception of green hues.

S Cones

A type of photoreceptor in the eye that is sensitive to short wavelength light, contributing to color vision.
