HSB color model

HSB color model

The HSB (Hue, Saturation, Brightness) model, also called HSV (Hue, Saturation, Value), defines a color space in terms of three constituent components:

bullet Hue, the color type (such as red, blue, or yellow). The hue is the part of the color independent of its brightness or dullness. For example, if we wanted to pick a dark red, we would start with a red hue and then simply make it darker by adjusting the lightness;
   bullet Ranges from 0-360 (but normalized to 0-100% in some applications).
bullet Saturation, the "vibrancy" of the color. Saturation, unlike lightness, determines how "colorful" a color is. A highly saturated color will be vibrant, like fluorescent yellow, whereas a completely desaturated color will be grey;
   bullet Ranges from 0-100%;
   bullet Also sometimes called the "purity" by analogy to the colorimetric quantities excitation purity and colorimetric purity;
   bullet The lower the saturation of a color, the more "grayness" is present and the more faded the color will appear, thus useful to define desaturation as the qualitative inverse of saturation.
bullet Brightness, the brightness of the color:
   bullet Ranges from 0-100%.
