romainmenke has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-color-4] Conversion examples give unexpected results (lab -> sRGB, lab -> P3, ...) == Have been working on a [postcss-lab-function](https://github.com/csstools/postcss-lab-function) and found some discrepancies in colors converted with the code found here : https://github.com/w3c/csswg-drafts/blob/main/css-color-4/conversions.js I am unsure if I am doing this wrong, or if there is a real issue. It might also be a bug in Safari as there is no other browser I can compare it with. Results : - lab : https://romainmenke.github.io/lab-lch-display-p3/lab.html - lch : https://romainmenke.github.io/lab-lch-display-p3/lch.html (Safari 15 supports all features, so can be used to compare) Code used in the conversion : https://github.com/romainmenke/lab-lch-display-p3/blob/main/conversion.js#L1-L60 - P3 values are used as is - sRGB values are multiplied by 255 Would be great to pinpoint were this goes wrong so that I am sure the plugin uses correct conversions.
