In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
of 2011-04-25 on 3249CTO
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (4.5) --no-opt --cflags
-Ic:/imagesupport/include'
1. The region is a dark blue that does not invert the black foreground. So
selected text is illegible.
2. When sending a bug report the To and Subject lines have yellow text (on a
white background). Illegible. Other text, such as "--text follows this line--"
is cyan on white - also too light a color to be legible.
3. About the only reasonable color used for sending a bug report is for the
field names (e.g. From:) - that uses a dark green. All the rest is ridiculous:
magenta, yellow, light cyan foregrounds on a white background - by default?
What were you thinking?

It never did. If we want to change the foreground, we need to specify
it for the `region' face.
> So selected text is illegible.
What foreground color is the selected text, and what is the background
of the `default' face?
In fact, could you please provide a recipe starting from "emacs -Q -nw"?

How did you get to the white background? The default background of
"emacs -nw" on Windows is black. Again, please provide a full recipe.
If I start with "emacs -Q -nw", then change the fore- and back-ground
colors of the `default' face to black and white, respectively (so at
least my background is as yours), then type "M-x report-emacs-bug", I
get the `message-header-name' whose foreground is "corneflower blue"
(mapped to cyan), not yellow. And the "--text follows this line--"
part is shown in brown (displays as a kind of light yellowish color).
They are quite legible (although the white background is too glaring
to my taste; but then it isn't the default). But you describe
entirely different colors.

I don't know what were "we" thinking, because I don't see any of these
colors when I try to reproduce this. Would you please show a complete
recipe, starting from "emacs -Q -nw", to reproduce these problems?

My point was only that a black foreground on dark blue is not wonderful.
But see below - I think I found the cause, if not the cure.

Black foreground. :background "unspecified-bg"
BTW, `M-x customize-face RET default RET' gives me a Customize buffer with a
bright yellow background on much of the buffer. See screenshot.

1. For region: emacs -nw, then select some text with the mouse: dark blue
background.
2. For the bug-reporting color:, emacs -nw, then `M-x report-emacs-bug RET
foobar RET'.
But see below.

I use a Windows shortcut that has this as Target:
C:\path-to\emacs.exe -nw -Q --debug-init "C:\drews-lisp-20"
Field Start in is C:\drews-lisp-20
Field Run is `Normal window'
However, and this is no doubt the cause of the problem, the shortcut also has
these settings for tab `Colors':
Screen background: Red, Green, Blue each 255
Selected screen colors: (black)
Selected pop-up colors: (a dark magenta/purple)
I do not set any Emacs faces (e.g. `region'). This Windows shortcut setting is
all I have. I would hope that Emacs could figure out that it is dealing with a
light background (dark foreground), but no, I don't know anything about how it
might do that.

See above. I just double-click my Windows XP shortcut, which is as described
above. HTH.

I think Emacs cannot figure out the background mode in a -nw session,
at least not in general. There's no interface to the text terminal
that can tell it that. But I will try to see if there's something
that can be done on Windows specifically.

OK, thanks. If nothing can be done then please close the bug.
I think I just copied my shortcut for ordinary Emacs without -nw and then added
the -nw. It works fine for ordinary (non -nw) Emacs.

I fixed this (in revno 104155 on the trunk). xterm.el already queries
the terminal about the background color, so I used a similar technique
to do the same on the w32 console, except that I needed a new
primitive for that.
I'm closing this bug. If you see anything wrong with how the new code
works with your shortcut, feel free to reopen it.
