Color theory is a set of rules for mixing colors and how they interact and influence each other to get a desired result. The standard color wheel supplies a system of color identification. Color hues consist of three primaries: red, yellow and blue, three secondary: orange, green and violet and six tertiary: red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet.
Analogous schemes are hues which are adjacent on the color wheel creating a harmonious scheme. Look to nature to discover analogous color schemes abundantly displayed in plants and flowers.
Complementary colors are on the opposite side of the color wheel; these colors generally enhance and intensify each other. Complementary colors can create a sense of enthusiasm and excitement based off their contrasting tones. Complementary color schemes work well when you use a warm color against a cool color. This color scheme offers a higher contrast than the analogous color scheme.
