This document discusses color theory and color schemes. It defines key color terms like hue and describes how colors have temperatures as being either warm or cool. Warm colors like red, yellow and orange advance visually, while cool colors like blue and green recede. Six common color schemes are described: monochromatic uses tints of a single hue; analogous uses neighboring hues; complementary are opposite hues; split-complementary uses a hue and neighbors of its complement; triadic uses three equally spaced hues; and neutral uses whites, grays and occasional accent colors. Examples are provided for each scheme using the color wheel.
