Colour vision in human eyes is the function of photoreceptor cells named
Cones
The correct answer is Cones.
Cones are retinal photoreceptors that work in bright light and provide colour vision and sharp (photopic) vision; three types respond to red, green and blue light.
Rods work in dim light and give black-and-white (scotopic) vision. The blind spot (optic disc) has no photoreceptors at all, and the fovea is a small pit packed with cones — a region of the retina, not a type of cell.
Short trick: Cones = Colour; Rods = dim light (night vision).
