According to opponent color theory what causes the perception of white?



Answer:

Opponent color theory - Our visual system maintains efficiency by measuring differences in the wavelengths being received by our three types of cones. There are three opponent color channels assigned to our cones: red v. green, blue v. yellow, and black v. white
Variances in luminance cause our perception of white. There are cones that are achromatic (black and white color channels) and more sensitive to changes in brightness (leading to our perception of black and white respectively)
