This document discusses color theory and the basics of working with pigments and dyes. It explains that primary colors are those that cannot be created by mixing other colors, and they can be used to make all other colors. Secondary colors are created by mixing equal parts of two primary colors, and tertiary colors are made by mixing a primary and a secondary color. The color wheel is used to visualize the relationships between colors, including complementary colors that are directly across from each other and contrasting versus harmonic color pairs. Other concepts covered include warm and cold colors, color saturation, value, and applying color theory principles to landscapes.
