Light
Color is actually from sunlight. Without the sun, everything would be black, white, and grey.

Sight
Now that we learned about color, we need to learn how we see. When light enter the pupil, and is focused through the cornea, lens, and iris. Then the image focuses on the retina. There are 2 types of cells in vision: Rods and cones. Rods see black, white, and grey. Cones see colors.
