Which part of the eye is responsible for color detection?

The part of the eye responsible for color detection is the cones. These photoreceptor cells are concentrated in the retina and are specifically designed to respond to different wavelengths of light, allowing us to perceive color. There are three types of cones, each sensitive to a specific range of wavelengths corresponding to red, green, and blue light. This trichromatic nature of color vision enables us to see a wide spectrum of colors by combining the signals from these three types of cones.

Rods, on the other hand, are primarily responsible for vision in low light conditions and do not contribute to color perception. The lens is involved in focusing light onto the retina, and while the iris regulates the amount of light entering the eye by controlling the size of the pupil, it does not play a role in color detection. Thus, the ability to detect color is solely reliant on the functioning of cones within the retina.
