Final answer:
Cones are the retinal cells that play a role in color vision. They contain three different photopigments that allow us to perceive colors.
Step-by-step explanation:
The type of retinal cell that plays a role in color vision is the cone photoreceptor. There are two major types of photoreceptor cells in the retina: rods and cones. Rods are responsible for peripheral vision and vision in very dark environments, while cones are specialized for color vision. Cones contain three different photopigments, called opsins, which are each sensitive to a specific wavelength of light, allowing us to perceive colors.
