Then perhaps you or someone else could suggest how to do that in
Emacs.

The code I showed exists since 2002, and it was not changed since
written.  If you know which older Emacs version didn't behave like
this, I'd be interested to know which one.

What do you see Emacs display in xterm for the colors?  I tried that
before I responded to you the first time, and saw the same E5E5E5
value.

I don't think it will change anything, because Emacs turns on tty
colors by their index (a small number between 0 and 7 or 15), not by
their RGB values.  If you succeed, please reopen the bug and tell what
changes were needed for that.
