the standard color wheel, expressed as a degree between 0° to 360°. In common use, hue is

identified by the name of the color such as red, green, orange, etc.

contained in a lookup table.

Lightness

This describes the intensity of a color and determines whether a color is closer to black or white.

primaries are specified separately and printed individually, it is important that the color is placed

in precise locations or the colors will not align to produce the desired result.
