The three-color theory was proposed by the British physicist Young in 1801, and later developed by Helmholtz, collectively known as the Young-Helmholtz three-color theory. This theory starts from the fact that the three primary colors of red, green, and blue can be mixed in different proportions to produce various hues and greys, and assumes that the excitation of the three nerve fibers in the retina can cause a sense of primary colors.
The three kinds of nerve fibers have their unique excitement levels for each wavelength of the spectrum, and when the light stimulation causes different degrees of excitement of the three fibers at the same time, various color perceptions are produced according to the corresponding ratio.
