Color in Nature
What physical mechanisms produce the colors around us?Models of physical color are simulated in the field ofcomputer graphics, and are essential to the production of the inks and dyes in print and film-plus, they are fascinating. The previous chapter described digital color, represented by numbers and additive mixture. This chapter describes various physical mechanisms for producing color, including absorption, refraction, and different types of scattering. It also introduces paints and dyes, the technologies for manufacturing color in the physical world.
