 Definition: 

(HSB) A colour model that describes colours in terms of hue, saturation, and brightness.

In the tables below, a hue is a "pure" colour, i.e. one with no black or white in it. A shade is a "dark" colour, i.e. one produced by mixing a hue with black. A tint is a "light" colour, i.e. one produced by mixing a hue with white. A tone is a colour produced by mixing a hue with a shade of grey.

microsoft windows colour dialogs, pageplus, and paint shop pro use hsb but call the third dimension "luminosity" or "lightness". It ranges from 0% (black) to 100% (white). A pure hue is 50% luminosity, 100% saturation.
