HLS color space

Redirected from HLS

The HLS color space, also called HSL, stands for "Hue, Saturation, Lightness." While the HSV (Hue Saturation Value) can be viewed graphically as a color cone or hexcone, HSL is drawn as a double cone or double hexcone. Both systems are deformed versions of the RGB colour cube. The two apexes of the HLS double hexcone correspond to black and white. The angular parameter corresponds to hue, distance from the axis corresponds to saturation, and distance along the black-white axis corresponds to lightness.
