Basic Color Principles When a beam of white light is passed through a prism, a spectrum of the entire range of pure colors visible to the naked eye is formed.

The Three Dimensions of Color Hue Value Chroma

Hue Hue identifies a color by name. Every color falls into a definite hue category as indicated by the spectrum color name on the color wheel.

Value Value is the lightness or darkness of a hue achieved by adding white, gray, or black. White added to a hue creates a tint. Gray added to a hue creates a tone. Black added to a hue creates a shade.

Chroma Chroma refers to the degree of intensity, strength, saturation, or purity of a color. Purity of a color refers to its freedom from white, black, or gray.

Primary Colors Red, blue, and yellow comprise the three primary colors. These three colors can approximate, through selective mixture, all of the other colors.

Secondary Colors Orange, violet, and green are the secondary colors. Each is placed between the two primaries that are mixed to produce it.

Primary & Secondary Colors

Color Harmony Complementary Split Complementary Triadic Analogous Monochromatic

Complementary Complementary color harmony features colors directly opposite on the color wheel.

Split Complementary Combining one color with two colors on either side of its direct complement results in a split complementary.

Triadic Triadic color harmony involves three colors equally spaced on the color wheel.

Analogous Analogous colors consist of related colors that are adjacent on the color wheel. They usually include only one primary color. Analogous color harmony allows one color to dominate and others to enhance.

Monochromatic Monochromatic color represents a harmony arrived at through variation in the value and intensity dimensions of a single color.

Color Balance Any color which dominates its immediate environment in hue, intensity or value will over balance a color or colors of lesser contrast and tend to divert attention from the composition.

Warm Colors Warm, or advancing colors, are those that resemble fire and heat. Red, red-violet, red-orange, and yellow-orange are examples of warm colors. Warm colors appear closer and are more eye catching than cool colors.

Cool Colors Cool, or receding colors, are associated with peace and calm. Blue, blue-green, and blue-violets represent cool colors. Cool colors in a composition tend to visually recede and look smaller. They are not easily seen from a distance.
