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:
- 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;
- Ranges from 0-360 (but normalized to 0-100% in some applications).
- 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;
- Ranges from 0-100%;
- Also sometimes called the "purity" by analogy to the colorimetric quantities excitation purity and colorimetric purity;
- 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.
- Brightness, the brightness of the color:
