Hue, Brightness, and Saturation
There are three main components to color: Hue, Brightness,
and Saturation.
Hue
The component that determines the frequency of light or
the position in the spectrum or the relative amounts of
red, green and blue. Hue corresponds to the common
definition of color, e.g. "red", "orange", "violet" etc.
Brightness
The component that determines the total amount of light
(white) in the color. Zero brightness is black. 100%
Brightness is white. Intermediate values are "light" or
"dark" colors.

color mode (color matching method).

Saturation
The degree of saturation of a color is its relative purity, or
freedom from, mixture with white.
