Color is a complex phenomenon that makes each person's experience of color distinct. As a result, we often have difficulty in communicating about color. This website is partially dedicated to overcoming this by defining color terminology using the COLORCUBE as the standard model for visualizing color concepts. Since we do not claim to be the utmost authorities on color, we invite you to challenge and debate our statements about the "dimensions of color".

Diagrams featuring Chroma Objects

Description: Often confused with saturation, chroma has more to do with the sharp brightness of a color rather than the general fullness of it. When a color is said to be "chromatic", it contains a hue that is spectrally pure. "Achromatic" or "monochromatic" colors, by contrast, are polluted by impurities and appear washed out and dull.

Inside the COLORCUBE: Graphs of constant chroma look like odd-shaped columnar rings around the grayscale (the colors that run between white and black).

Behaviour: As chroma increases, color moves from the grayscale to the furthest edges of the color space.

Alternate terms: Chromaticity, Purity

Examples: High Chroma = "fire engine red", "canary yellow". Low chroma = faded blue jeans
