Thanks, but what exactly is the purpose of this change?

The more colors that need to be allocated, the slower Emacs becomes over
a wide-area network.  In addition, every time a new color is used,
xfont_draw needs to be called again, generating more network traffic.

Emacs has already become quite slow over a network connection (though
this should have become significantly better in Emacs 29.)

Adding "eye candy" where it is not really necessary will only be a step
backwards.

I guess if it is off by default, then I have no objections.  But I
respectfully ask everyone to keep in mind the network impact of changes
they make to Emacs.
