Answer is opponent-process theory.
Further explanation
Color vision
Color vision is a capacity to see contrasts between light made out of various wavelengths freely of light force. Shading recognition is a piece of the bigger visual framework and is intervened by a mind complex process between neurons that starts with differential stimulation of various kinds of photoreceptors by light entering the eye. Those photoreceptors then transmit yields that are then engendered through numerous layers of neurons and afterward at last to the cerebrum.
Color blindness
Such condition in which an animal cannot differentiate in colors.
Types of color vision
Monochromacy
It is in marine mammals.
Dichromacy
It is present in non-primate mammals.
Trichromacy
It is seen in primates.
Tetrachromacy
Mostly in amphibians and reptiles.
Pentachromacy
Mostly in birds and insects.
Theories of color vision
Color vision theories are following .
Trichromatic Theory
The trichromatic theory of color vision, otherwise called the Young-Helmholtz hypothesis, expresses that the retina has three receptor cells, which respond to light of three unique wavelengths - red, green and blue. These cells are in charge of the impression of colors.
Opponent-Process Theory
Given by Ewald Hering, the adversary procedure hypothesis expresses that the cone photoreceptors are connected together to frame three contradicting shading sets: blue/yellow, red/green, and dark/white. Initiation of one individual from the pair restrains action in the other. Predictable with this hypothesis, no two individuals from a couple can be seen at a similar area, which clarifies why we don't experience such hues as "somewhat blue yellow" or "red green". This hypothesis likewise clarifies a few sorts of shading vision inadequacy. For instance, individuals with dichromatic lacks can coordinate a test field utilizing just two primaries. Depending upon the lack they will confuse either red and green or blue and yellow.
