May 18, 2017 at 20:30 comment added ChemiCalChems I've always assumed different cones detect different color wave lengths because some molecules in them get excited only by those wavelengths of light, and then give off the energy in some other way. It seems to be the only explanation I can find, but of course, I know nothing about biology, just some chemistry and physics.
