Hue: The name given to a color to describe its location on the color spectrum based upon its wavelength. Also called Chroma or color.

Additive Color: Color as seen in light Additive Color: Color as seen in light. Additive color primaries are red, green, and blue-violet. When combined, the result is white light. The more you add color, the brighter the colors become

Subtractive Color: Color seen in pigment as the result of reflected light. Subtractive color primaries are red, yellow and blue, and when they are combined, they produce a dark tone that approaches black. When you combine them, they subtract.

Hue continuum: A graphic representation of the full color spectrum from red to violet. A 360 degree strip.

Color Wheel: A circular depiction of various colors and their relationships traditionally used to illustrate aspects of a particular color theory.

Triadic Hues: Color relationships based on any three equidistant hues as shown on the color wheel

Primary Triad: called so because theoretically they can be mixed to form all other colors. In subtractive color they are red, yellow and blue.

Primary Triad

Secondary Triad: another triadic relationship on the wheel Secondary Triad: another triadic relationship on the wheel. They are called secondary because In subtractive color, these colors can be made by combining two primaries.

Secondary Triad

Tertiary double triad: hues resulting from the combination of a primary color with a secondary color.

Tertiary Double Triad

Complementary Hues: Hues that lie directly across from each other on the color wheel

Analagous Hues: Hues that lie adjacent to each other on the color wheel

Split complement: particular complementary relationship made by creating a three color analogous set from the oppositional color.

Scintillation: a vibrating or dissonant effect that occurs when complementary or split complementary colors are placed next to one another.
