Cone cells come in three types — red light, blue light, and green light — and they not only help us to see red, blue, and green, but they work together to see all colors. WebThe way our eye sees and processes color is conceptually simple but very important. The brain and eyes are connected by the optic nerve, which transports the images of the world we see to the brain for processing. In the eye, there are two different types of photoreceptors- rods and cones. ctl.cl web
