I think this would be good to allow use of names like this, without necessarily hardcoding them in the standards, because there are so many naming schemes out there that if we start down that route, we going to be standardizing color names for the rest of our lives.

First, you can already sort of roll your own using custom propoerties

:root {
--md-red-a400: #ff1744;
--md-red-500: #f44336;
foo {
  background: var(--md-red-500);

Support is already pretty decent:

Further down, css-color level 4 offers a mechanism that would allow for a nicer and more specialized syntax:

@color-profile md {
  src: url("https://www.exammple.com/material-design-colors.icc");

foo {
  background: color(md, "red-500");
