This document discusses color theory and color schemes. It explains that color is derived from reflected light and is determined by an object's hue, value (lightness or darkness), and intensity (brightness). A color wheel is used to demonstrate the primary, secondary, and complementary colors. Different color schemes are described including monochromatic, analogous, complementary, triadic, and split-complementary. The document also explores how artists use color expressively and how our perception of color depends on context.
