| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: struct
Returns the saturation value of the argument, which must be an hls color object. See make-hls.
Note that the value of color properties (such as background-color and foreground-color) must be RGB color objects, as made with make-rgb. You should apply the function hls-to-rgb to an HLS color before setting a color property to it. You can use the function rgb-to-hls to get the HLS equivalent of an RGB color.
