Re: [csswg-drafts] [css-color-4] Should the color() function accept 'lab' as a color gamut keyword (#4649)

Ah. No, XYZ is independent of whitepoint. What I mean is that with relative XYZ, the luminance (Y) is scaled to 100 for the media white; while for absolute XYZ the Y is in candelas per square meter (so can take a very wide range of real-world values).

I'm not sure what XYZ adds, from an authoring standpoint. It is more user-hostile then sRGB (but is at least linear-light, not gamma corrected). I'm aware it is one of the two profile connection spaces in an ICC workflow (the other is D50 Lab), which I suspect is why you suggested it?
