In case my approach is of use, for "non production" Emacs versions or
instances, I change the background color of the mode-line and set the color
of 'internal-border. I set a "test flag" either on version or by
command-line argument "--test". The mode-line color shows fine in tty and
GUI. I can't easily get confused that way.
