What are the visual receptors that process color called?

Cones
Rods
Lens
Retina

The correct answer is: Cones

Cones are the visual receptors in the retina that are responsible for processing color vision. They are concentrated in the central part of the retina, specifically in the macula. Cones contain different pigments that allow the detection of different colors within the visual spectrum. In contrast, rods are responsible for vision in low-light conditions and do not contribute significantly to color vision. The lens of the eye is responsible for focusing light onto the retina, and the retina itself contains both rods and cones, with cones specifically related to color processing.
