This document discusses various elements of color including hue, value, pattern, and texture. It defines these terms and provides examples to illustrate key concepts. Hue refers to the pure spectrum colors, while value is the lightness or darkness of a color. Pattern is an underlying structure that organizes surfaces in a consistent manner, seen in both nature and design. Texture can be both a literal surface felt through touch and a surface suggested through vision by invoking the sense of touch.
