Summary
This adds data on the individual values of the
color-gamutmedia query.Test results and supporting details
All browsers parse the media query and all its values; see the web platform tests for feature color-gamut.
However, Firefox does not support displays with a wider gamut (or, strictly speaking, it works only in sRGB and hands off color management to the OS), so the values other than
srgbare always false. This does not mean the media query is unsupported (as suggested by #21422). This is the correct behavior given by the spec (emphasis added):This might be slightly surprising if you have a P3 display connected. I've added notes to capture this nuance, similar to what I've done in #28868.
