Hello

Really nice work!!! How does it compare with HSLuv (https://www.hsluv.org/)? It seems that both scheme try to manage the perceptual color problem...

That is based on CIELUV, which is one of the spaces tested against in the article. CIELUV is useful because its chromaticity space is a projective transform of XYZ. That also means it doesn't predict perception of hue as well as more complex models.
