## rgb-to-hls

Arguments: rgb-triple

Returns the hls color object corresponding to the argument rgb color object. See make-rgb, make-hls and hls-to-rgb.

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.
