Make a list of regexp matches... perhaps
already in Emacs/ELPA/Joe Hacker's stash/etc?
Improvements AND comment look like this:

If you don't mind the matches being returned in reverse order, that's
fine. Otherwise you might consider returning (reverse matches).
In your case, since you build a fresh list which nobody else sees,
you might get away returning (nreverse matches) without the Functional
Gods frowning at you ;-)

Actually it will be visible indeed :)
Because I now have a LED-keyboard and I thought
I'd have a function that gave a fresh color
randomly, but not too randomly, still colors
that made sense...
So I got the list from the web but it still
needs some computing...
As for now, 'warmy' is the most creative:

It seems I was unclear. I was talking about your variable
"matches", which you create whithin the function and let
grow with each match found. Since that variable is not
visible outside the function's scope, you can afford the
(potentially) more efficient nreverse.
Sorry for the confusion. Just ignore if still unclear :)

Then you've got all you need for a founded choice.
(or (ignore) (unignore)) I'd say :-)

Usually converting to CPS is a good first step to solve these kinds
of problems.

You mean you never heard of the
continuation-passing style?
In functional programming, continuation-passing
style (CPS) is a style of programming in which
control is passed explicitly in the form of
a continuation. This is contrasted with direct
style ... [1]
It makes so much sense - Emanuel Berg's style
being so direct, I mean :)

CPS seems to be some version of recursion but
where instead of removing an item from a list
or decreasing a digit one provides f1(a f2) and
it is the function that changes fn..f2(f1(a))
until it and thus the whole thing terminates.
So f2 is the "explicit continuation function"
[1] to f1, the one that gets called after f1
has done its operations on the value
original argument.
Maybe?

If CPS is about like with `reverse' and
`nreverse', which I take it are the quadratic
and linear versions of the same unelegant last
thing of reversing all good enough government
job already done, then relax, one can do it
with the "direct" style as well - and even
directly so, by just fliping the first
`re-make-list', which is direct to begin with!

I didn't realize how CPS is not just technically a good first step, but
also at a more meta-level it's proved a great first step!

Ho ho
But no one has suggested
Standard META Language!
Added CPS to another list [1]
CPS 1975 continuation-passing style, coined in "AI Memo 349"
so thank you :)
In the Debian repos are libcps-perl!
Nothing in M/ELPA... (?)
In Emacs, how about
cps--add-binding cps--add-state
cps--advance-for cps--atomic-p
cps--define-unsupported cps--find-special-form-handler
