Color Perception

Rods and Cones

• But actually, color is determined by our brain, not our eyes.

• (And not by the frequency of the light waves hitting our eyes.)

• People with very different quantities of cones perceive the same colors. http://www.sciencedaily.com/releases/2005/10/051026082313.htm

• The same color perception can be caused by different spectra of light.

And, illusions

The squares marked A and B are the same shade of gray.

Pink? Fuschia? Magenta?

In conclusion

Color perception, like games and like all of art and much of life, is an experience.
