On a white mrxt black on white terminal[1], the font-lock colors are
unreadable. See attached picture.
$ tput colors
8
Please improve font-lock-keywords.

It appears that emacs thinks that you have dark background. What did
you set TERM to?
This looks like it is an rxvt derivative, so the value of the COLORFGBG
environment variable should help emacs realize what is the default
background.

I started mrxvt from xterm:
$ xterm
$ echo $TERM
xterm
$ mrxvt &
mrxvt$ echo $TERM
rxvt
<terminal is open in black on white>

mrxvt$ COLORFGBG=1 emacs -Q -nw
=> Same color results as in previously attached picture

It works just fine for me on Fedora 10, with emacs CVS HEAD, emacs-22.3
on either rxvt and mrxvt.

I can reproduce this on an xterm brought up on OS X in Emacs 25, so I'm
removing the unreproducible tag.
IMHO, Emacs should have a way to configure all faces to be legible. We
already have shr-color-check thanks to Julien Danjou, it should be an
interesting project for someone to use that to correct all faces. I
think trying to squash each instance of an illegible font without that
sort of solution would be a never-ending task, considering all the
themes out there.

That sounds like an enhancement to me, so I think we should tag this
bug report "wishlist". WDYT?

Sure, let's consider this a wishlist for the general feature of not
having these kinds of unreadable colors. I'll tag this as you suggest.

I'm not sure what the COLORFGBG is, so I tried:
<mrxvt terminal: black text on white background>
COLORFGBG="dark;light" emacs -Q -q -nw ~/tmp/test.el
COLORFGBG="light;dark" emacs -Q -q -nw ~/tmp/test.el
COLORFGBG="default;default" emacs -Q -q -nw ~/tmp/test.el
with same results as in previously attached picture. No change.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
The problem here was that Emacs often didn't manage to determine the
correct background colours on terminals. I believe that his has been
fixed now, so I'm closing this bug report. If there are still problems
here, please respond to the debbugs address and we'll reopen.
