Question

How is color sensitivity of the eye correlated to the distribution of the rods and cones?

Answer 1

Humans have two types of photoreceptors: rods and cones. Rods are used primarily to see at low levels of light, while cones are used to determine color, depth, and intensity. Furthermore, there are three types of cones, which aabsorb different wavelengths of photons and therefore "see" different colors. Color vision requires interactions of more than one type of cone, primarily by comparing responses across different cone types.
