HSB color (hue, saturation, and brightness) is just another term for HSV
(hue, saturation, and value). Allegro contains functions for converting
between RGB and HSV formats.

You may also sometimes run into the HLS format (hue, lightness, and
saturation). This is a slightly deformed version of HSV color, where
zero lightness represents black, one represents white, and 0.5 is a
fully saturated chromatic color.

Check out Foley & Van Dam, "Computer Graphics, Principles and Practice"
for a good discussion of the various color spaces.
