Toggle navigation HUSL Implementations Comparison Math Demo HUSL is a human-friendly alternative to HSL . To the left Above you can see CIELUV , 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. HUSL extends CIELUV with a new saturation component that allows you to span all the available chroma as a neat percentage. H S L HUSL is implemented as a set of functions to convert colors between RGB, HUSL and HUSLp. Check the individual ports for documentation and licensing. Most of the code is released under the MIT license. The math is available under the public domain. The reference implementation is in JavaScript. This code is...
