In the retina are sticks and pegs. Stäbchen are there for light / dark, the pins for color separation. The optic nerve forwards the information from the retina to the brain. At the place where the optic nerve lies in the retina, you are blind. This is the blind spot, also called papillary or puppet meat.

You must first distinguish between colour-blind and colour-weak. These are two different things. A colour-blind person sees only gray because he has no cups on the retina or black/white, with him the cups are either small or defective.
