Color - (HSV|HSI|HSL) (Hue, Saturation) (Value|Intensity|Lightness) Color Space

1 - About

The (HSV|HSB|HSI|HSB|HSL) color space is based on:

The HS* color spaces are simple geometric transformations of the RGB cube into cylindrical form.

The variables are assigned to cylindrical coordinates in an attempt to be more intuitive and perceptually relevant than the RGB cartesian (cube) representation.

3 - Cylinder

In each cylinder:

  • the angle around the central vertical axis corresponds to “hue”,
  • the distance from the axis corresponds to “saturation”,
  • and the distance along the axis corresponds to “lightness (value)” or “brightness”.
