The HSL color space model can be graphically illustrated as a three dimensional cone.
Hue is represented by an angle around the base of the cone, as seen below, while
saturation is represented by a colors distance from the center of the cone to the edge,
with the center being completely desaturated and the edge being saturated to
maximum intensity. A color’s brightness, then, can be represented by its distance from
the base to the peak of the cone.
Color actually provides a three-dimensional video scope thats capable of displaying
the colors of an image within an extruded HSL space, for purposes of image analysis.
