[csswg-drafts] [css-color] Working Color Space

svgeesus has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-color] Working Color Space ==
https://drafts.csswg.org/css-color/#working-color-space
> Resolved at San Francisco to add a working-color-space at-rule, 
which affects the entire document. Compositing, interpolation, 
blending use this. Initial value is sRGB. linear-sRGB, p3, rec2020, 
and lab were also discussed as values. Chris to read the canvas spec 
to see what it does there, particularly for the "optimal" value.
