I did a lot of research on color naming relatively recently. The very
real problem is that there are not nearly enough color names to cover
every possible value, even before alpha and color profile are factored
into the scope. That means, even with CSS colors, X11 colors, Crayola,
and the formerly expanded Pantone catalog, we're still well short.
Believe it or not, HEX actually is the most fitting and covers the
widest spectrum.
I've since approached the folks at schema.org to discuss what a
standardized color schema could look like.

You'll want to look at the draft CSS Color Level 4 specification section
on defining colors relative to device-calibrated color profiles:
This syntax is designed to be extensible to any new color-definition
system against which printers and digital displays could be calibrated.
Although the pre-defined profiles currently in the spec use numeric
values, keyword values are also possible.
Given the wide use of Pantone colours in printing and industrial design,
I'm suspect CSS WG members would be open to integrating it in the spec
as a pre-defined color profile, if all IP issues could be resolved with
Pantone in a manner that met W3C's patent requirements.
Otherwise, the syntax is designed to allow authors & printers/display
manufacturers to specify custom color systems without them having to be
added to the spec.
All of this is still a separate issue from calibrating printers / and
digital displays against Pantone standards, so that they correctly
display the named color.  As others have mentioned, that's a tricky
question when dealing with web content.  However, the new syntax would
ensure that *if* the display or printer is calibrated, authors would
have a standard way of communicating the desired color.
(PS, I'm not a member of this working group, just someone who's been
following the discussion.  Chris Lilley & Tab Atkins, the editors of CSS
Color Level 4, would be your best contacts for deciding on next steps.)
