This document discusses color and light. It explains that objects absorb all colors except the one we see reflected. The amount of available light affects how clearly we see color and detail. Cones in our eyes see color best while rods see shapes in low light. There are three types of color cones receptive to red, green, and blue light. The document also discusses additive color, subtractive color, hue, value, saturation, transparency, opacity, color blindness, color wheels, monochromatic color schemes, analogous color schemes, complementary color schemes, triadic color schemes, and split-complementary color schemes.
