Hsluv color space conversions
This package provides an elisp implementation of the HSLUV colorspace conversions as created by Alexei Boronine, and 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. The reference implementation is written in Haxe and released under the MIT license. It can be found at https://github.com/hsluv/hsluv The math is available under the public domain. The following functions provide the conversions from RGB to/from HSLUV and HPLUV: (hsluv-hsluv-to-rgb (list H S Luv)) (hsluv-hpluv-to-rgb (list H P Luv)) (hsluv-rgb-to-hsluv (list R G B)) (hsluv-rgb-to-hpluv (list R G B)) Changelog 2017/04/15 v1.0 First version 2018/08/07 Split off testing 2018/10/13 Cleanup for package release in the wild
