Hue, saturation, brightness




<graphics> (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.

Quattro Pro, CorelDraw, and PhotoShop use a variant (Quattro Pro calls the third parameter "brightness") in which a brightness of 100% can produce white, a pure hue, or anything in between, depending on the saturation.
