Description Nikita Vasilyev 2020-05-14 16:10:23 PDT 
Web Inspector shows "Unsupported property value" for

    color(display-p3 1 0.5 0.6, pink)

"pink" here is a fallback value. Web Inspector should parse it as a valid color.

10.1. Specifying profiled colors: the color() function

The color() function allows a color to be specified in a particular colorspace (rather than the implicit sRGB colorspace that the other color functions operate in). Its syntax is:

color() = color( [ <ident>? [ <number>+ | <string> ] [ / <alpha-value> ]? ]# , <color>? )
The color function takes one or more comma-separated arguments, with each argument specifying a color, and later colors acting as "fallback" if an earlier color can’t be displayed (for example, if the colorspace it specifies hasn’t been loaded yet).

Fallback colors have been removed from the spec.
