The trichromatic theory proposes that the retina has three types of color receptors, which are sensitive to one of three colors: red, green, or blue.
The trichromatic theory asserts that there are three distinct cone systems in the eye that perceive three types of color: blue, green, and red. It is based on the combined works of the 19th-century scientists Young and Helmholtz. Every combination of colors that the brain perceives is made up of three colors: blue, green, and red, in accordance with the trichromatic hypothesis.
S-, M-, and L-cones, respectively, are the cones in the brain that correspond to blue, green, and red on a physiological level. Blue-yellow color blindness is caused by the loss of S cones, whereas red-green color blindness is caused by the loss of M or L cones.
