for someone with full color vision, three (often refered to as short, medium and long). Each one is maximally sensitive to a different wavelength. These are found in the cones. People with color deficits have only two pigments, which is why they have difficulty coding for some parts of the visual spectrum, such as yellow/blue, or much more rarely, red/green. Someone with true colorblindness has only rods, so they only have one visual pigment molocule, and can't code for color at all.

Rods are the primary pigments in the retina of eye detecting black and white light or objects.
Yes. it is also called Retinol (because it produces the pigments for the retina of the eye) and Carotenoids (dark colored pigments in plant foods, like carrots and spinach).
Because the cells in the retina of the eye do not contain pigments that absorb these wavelengths.
Rods and cones contain the pigments that absorb light.
There are many pigments.Colored pigments are mainly Carotene and Xanthophyll.

Yes!There are other pigments, such as the yellow and orange plant pigments. These pigments give fall plants, many fruits, flowers, and vegetables their color. These pigments are known as carotenoids.

the retina contains the rods and cones which sense the amount of light and different colors respectively.
