Document Summary

Color is not a physical property of things in the world, it is a creation of the mind. Blood looks red because we look at it with our particular visual systems. Apparent color of a bit of the world is correlated with the wavelengths of the light rays reaching the eye from that bit of the world. Some wavelengths are absorbed by the surfaces they hit, the more light that is absorbed, that darker the surface will appear. Color of a surface depends on the mix of wavelengths that reach the eye from the surface. Color is the result of the interaction of physical stimulus with a particular nervous system. Discrimination: must be able to tell the different between one wavelength and another. Appearance: want to assign perceived colors to lights and surfaces in the world. Want perceived colors to go with the object and not to change dramatically as the viewing conditions change.
