Sure, I'm am just taking Pantone as an example to illustrate the point.
From a license standpoint, this couldn't happen without their involvement.
But the mechanism to use such colors would follow this kind of syntax.

The remaining question is how would this be declared. Do ICC profiles
have a way of defining named colors? If not, is there a standard
format for mapping names to the CIE XYZ or Lab color spaces? If not,
do we just add syntax to the @rule to handle this?

@colors "bad-taste" {
  profile: sRGB;
  color: "best-blue" 0 64 196;
  color: "best-grey" 42 42 42;
}

background: color("bad-taste" "best-grey");
