Located in the center of the retina (fovea) Retinal response (% maximum) v. wavelength of light (nm) 3 different types of cones to color sensitivity: red, blue, green. Combine to allow us to (cid:494)see the rainbow(cid:495) Cone photoreceptors are linked together to form there opposing pairs: blue/yellow, red/green, and black/white.
