Young-Helmholtz theory

Explanation

Young–Helmholtz theory is a trichromatic theory of color vision that explains how human eyes perceive vision by reacting to the wavelengths of light falling on the retina. Eyes have three types of cone cells – short-wavelength preferring, medium-wavelength preferring and long-wavelength preferring. The difference in wavelengths detected by the brain from the retina gives the color perception.
