The retinex theory of color vision emphasizes the influence of

A) genetically determined differences among human observers.
B) culturally determined differences among human observers.
C) comparisons from what you see in different parts of the visual field.
D) the ratio between the wavelengths of light and the intensity of the light.

The retinex theory of color vision suggests that color perception is based on comparisons of the light that objects reflect to what is seen in adjacent areas of the visual field. In other words, it emphasizes the influence of the comparisons from what you see in different parts of the visual field, as opposed to genetically or culturally determined differences or the ratio between wavelengths and intensity of light.
