This package provides an elisp implementation of the HSLUV colorspace conversions documented on http://www.hsluv.org/. 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.
