Which types of cells primarily contain cones for color vision?

The correct answer is that photoreceptor cells primarily contain cones for color vision. In the human retina, there are two main types of photoreceptor cells: rods and cones. Cones are specifically designed for daylight vision and are sensitive to color. They allow us to perceive a wide range of colors, thanks to three different types of cones that are responsive to various wavelengths of light corresponding to blue, green, and red.

While rods also play a crucial role in vision, particularly in low-light conditions, they do not contribute to color vision as they are sensitive to light intensity rather than color. Retinal ganglion cells are involved in processing visual information received from the photoreceptor cells, but they do not contain cones themselves. Therefore, the primary role of color detection lies within the photoreceptor cells, specifically the cones.
