The document discusses color terminology and color theory. It explains that red, yellow, and blue are the primary colors from which all other colors are derived. The secondary colors of orange, green, and purple are created by mixing two primary colors. Tertiary colors are made from mixing a primary and secondary color adjacent on the color wheel. Color schemes include monochromatic using tones of one color, analogous using neighboring colors, complementary using opposite colors, triadic using three colors equally spaced, split-complementary, and achromatic using black, white and grays. Understanding color properties like hue, value, warmth and coolness is important for successful color combinations.
