PSYC 3 Lecture Notes - Lecture 15: Color Vision, Additive Color, Opponent Process
Document Summary
Energy that is redirected when it strikes a surface, usually back to its point of origin. What is not reflected is absorbed by the medium. Our perception of color is based on what wavelengths hit the retina which are the wavelengths that are reflected by the medium. If an object is a color then it means some wavelngths are being absorbed. So a bright red object is reflecting only light of a wavelength of. 560 nm and absorbing other wavelengths of light into the thing. The perception of white is something that is reflecting . If object is a color, not black or white, then its absorbing some and reflecting. Ability to distinguish ripe from unripe fruit. Difficult for other animals to hide by camouflage. Can make any color by mixing the three colors. Any color could be reproduced by mixing various quantities of three colors. 3 different types of photoreceptors are sensitive to differing wavelengths of light.
