A Color Bar is a widget which controls the brightness (value) of a color by
means of the hue, saturation, value specification system. It is most useful
when used together with the Color Wheel which controls the hue and
saturation. The options COLORBAR_HORIZONTAL and
COLORBAR_VERTICAL control the orientation of the bar.
