+conversions documented on @url{}.  HSLuv is a
+human-friendly alternative to HSL.  CIELUV is a color space designed for
+perceptual uniformity based on human experiments.  When accessed by polar
+coordinates, it becomes functionally similar to HSL with a single problem: its
+chroma component doesn't fit into a specific range.  HSLuv extends CIELUV with
+a new saturation component that allows you to span all the available chroma as
+a neat percentage.")
