Re: [csswg-drafts] [css-color4] Precision issues when converting colors between Lab and sRGB (#5262)

I found it super confusing to store everything in one class and ended up implementing 3 classes: each for sRGB, Lab and XYZ color spaces with default D65 white point for sRGB, D50 for Lab and toggleable white point for XYZ using Bradford adaptation. Here's the repo:
(early stage without description at this point)

I've increased rounding from 3 to 7 decimal places and everything works perfectly fine now. 👍
The problem in particular was with Lightness of Lab which I stored as decimal in [0..1] range and in this way rounding to 3 places is not enough
