Detailed explanation-1: -The trichromatic theory of color vision is a theory that states there are three different color receptors in the retina. The cones in the retina are what give color vision. This theory says the cones are sensitive to three different colors: green, blue, and red.

Detailed explanation-2: -Young-Helmholtz theory-the theory that the retina contains three different color receptors-one most sensitive to red, one to green, one to blue-which when stimulated in combination, can produce the perception of any color.

Detailed explanation-3: -Trichromatic theory indicates that we can receive 3 types of colors (red, green, and blue) and that the cones vary the ratio of neural activity (Like a projection T.V.). The ratio of each color to the other then determines the exact color that we see.

Detailed explanation-4: -The Young–Helmholtz theory (based on the work of Thomas Young and Hermann von Helmholtz in the 19th century), also known as the trichromatic theory, is a theory of trichromatic color vision – the manner in which the visual system gives rise to the phenomenological experience of color.

Detailed explanation-5: -He also proposed that it was the strength of the signals detected by the receptor cells that determined how the brain interpreted color in the environment. Helmholtz discovered that people with normal color vision need three wavelengths of light to create different colors through a series of experiments.
