Thinking a bit laterally, there are 2 alternate mechanisms that
could help (at the loss of some flexibility):

1. There are named colors, such as "royal blue" that one can use
instead of "#RRGGBB" format. If it were possible to user-define
more, that would be a solution.

This is possible on X11, but not in the manner you mean: Those named colors are actually provided by the system.

Emacs bundles a copy of a historic de-facto standard set of named colors for non-x11 use. The set of named colors adopted by modern web browsers was also largely based on that set, with some small changes [1].

However on real X11 (at least x.org and friends), the set of named colors is user-extensible e.g. if you place the following in ~/.xcms.txt

Blobby  RGB:7fe2/ffe1/331a

and then

export XCMSDB=~/.xcms.txt

and run emacs in that environment, you'll have the color "blobby" available in emacs (and any other x11 app which uses the relevant x11 color api).

None of that means emacs couldn't support internal user-defined named colors, or any number of other things [2], just pointing out where they currently come from.

[2] e.g. I suggested - not too seriously - note the "may be overcomplicating things" - an ability to indirect through alists when resolving colors last time the matter came up:
