> > Ultimately, I don't think authors relying on colors outside the gamut that the color-gamut media query resolves to is all that useful a thing for authors (e.g. how important that on a display that has a gamut between P3 and Rec2020, out of P3 gamut colors get fully realized?) > > We will see this increasingly, as video content creators extend beyond DCI-P3 as a mastering volume and consumer displays (mainly TVs, to start) push beyond P3. The actual content is delivered in a BT.2020 or BT.2100 container, but does not use the fulll 2020 gamut. And displays will not go all the way to full 2020 for some time, because of the issues of luminous efficiency, speckle, and strong observer metamerism for genuinely single-wavelength display primaries. Hi @svgeesus, I was trying to limit the thought experiment to CSS color's as used by authors. Given we don't expect images video to use the same gamut mapping, being able to rely on them to match author specified colors out side of the gamut seems unlikely to be practical or useful. That said, if we think there are going to be common displays between Display-P3 and Rec2020, we should consider (with the clear caution and understanding that it will increase the finger printing surface area) adding to the list of color-gamuts that the media query can match against. -- GitHub Notification of comment by weinig Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/7610#issuecomment-1219639647 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
