The distribution of energy emitted by a radiant source, arranged in order of wavelength, esp. the band of colors produced when sunlight is refracted an dispersed by a prism, comprising red, orange, yellow, green, blue, indigo, and violet.

Designating a color having high lightness and low saturation.

Designating a color having high lightness and strong saturation.

Designating a color having low lightness and low saturation.

Designating a color having low lightness and strong saturation.

A system for specifying colors arranged in three orderly scales of uniform visual steps according to hue, chroma, and value.

One of the three dimensions of color. The property of light by which the color of an object is classified as being red, yellow, green or blue, or an intermediate between any contiguous pair of these colors.

One of the three dimensions of color, The purity or vividness of a hue, Also called intensity.

The degree by which a color differs from a gray of the same lightness or brightness, corresponding to saturation of the perceived color.

The dimension of color by which an object appears to reflect more or less of the incident light, varying from black to white for surface colors and from black to colorless for transparent volume colors.

The degree by which a color appears to reflect more or less of the incident light, corresponding to lightness of the perceived color.

The dimension of a color which is correlated with luminance and by which visual stimuli are ordered continuously from very dim to very bright.

A scale of achromatic colors having several, usually ten, equal gradations ranging from white to black.

The merging of juxtaposed dots or strokes of pure colors when seem from a distance to produce a hue often more luminous than that available from a premixed pigment.

The perceived color of an object, determined by the wavelengths of the light reflected from its surface after selective absorption of other wavelengths of the incident light.

The absorption of certain wavelengths of the light incident on a colored surface, the remaining portion being reflected or transmitted.

A color produced by mixing, cyan, yellow, and magenta pigments, each of which absorbs certain wavelengths. A balanced mixture of these colorant or subtractive primaries theoretically yields black since it absorbs all wavelengths of visible light.

A circular scale of the colors of the spectrum, showing complementary colors opposite each other.

Red, Yellow, and Blue

A color produced by mixing two primary colors.

Orange, Green, or violet.

A color produced by mixing two secondary colors,

or a secondary color with one of its constituent primaries.

Designating a color inclined toward or dominated by red,

orange or yellow.

Designating a color inclined toward or dominated by green,

blue, or violet.

A warm color that appears to move toward an

observer, giving an illusion of space.

A cool color that appears to move away from an

observer giving an illusion of space.

An arrangement or pattern of colors conceived of as forming an integrated whole.

One of a pair of opposing colors on a color wheel perceived as completing or enhancing each other.

One of two or three closely related colors on a color wheel.

A combination of one color and the pair of colors adjoining its complementary color on a color wheel.

A combination of two analogous colors and their complementary colors on a color wheel.

A combination of three colors forming an equilateral triangle on a color wheel.

Having only one color or exhibiting varying intensities and values of a single hue.

Having or exhibiting a variety of colors.

A triangular diagram developed to describe the relationship between a pure hue, white, and black, which combine to yield secondary tints, tones, shades and grays.

A relatively light value of a color produced by adding white

to it.

An intermediate value of a color between a tint and a

shade.

An achromatic color between white and black.

Having no saturation and therefore no hue, as

white, black, or gray.

A relatively dark value of a color produced by adding

black to it.
