8.1 version

hls-p

Arguments: object

Returns true if object is an hls color object and returns nil otherwise. 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.
