Red, yellow and blue are the primary colors that can be mixed to create all other colors. Secondary colors are created by mixing two primary colors - orange from red and yellow, green from yellow and blue, and purple from red and blue. Complementary colors sit opposite each other on the color wheel and analogous colors sit next to each other, both making pleasant color combinations. Tertiary colors are created by mixing a primary and secondary color. The document provides information about different types of colors and how they can be created through mixing primary colors.
