Document Summary
Half of a one sided 8. 5x11 inch cheat sheet. 20 min video - brain games : color. After staring at a the same color, your eye"s photoreceptors for that color will get tired. And them when picture switches from weird colors to black and white you will still see color. Black color absorbs every other wavelength of light. All of the light you see is from a light source or emitted from a surface. A leaf is unable to absorb green light, so green light bounces off it and you see green, but it"s actually every color but green. Color constancy - see colors that are reliable rather than the way they are. Differential absorption of light waves; everything reflected is what you see. Dictionary definition : the hue or appearance that a body presents to the eye. (not really correct) Define : the perceived difference in wavelength light intensity.
