The document discusses different color schemes that can be used in design based on relationships between colors on the color wheel, noting that color schemes can significantly impact a space by making it feel warmer, cooler, larger or more intimate and that common schemes include monochromatic using tints of one color, analogous using adjacent colors on the wheel, complementary using opposite colors, split-complementary, triadic using three equally spaced colors, neutrals alone or with an accent color.
