In Libreoffice Impress the text with the color "automatic" is hard to
read if the background color is set to black (example file attached). I
have to change the color from "automatic" to white.

Please map the "automatic" color to white if the background color is set
to black.

I could not reproduce this problem in 3.3.1 SLED 11 sp1.

1. In attached sample,  set the font color to automatic =>the text is
normally white

2. Change page background as solid white => the text turns to be black
as expected

3. Change page background as solid black back => the text turns to be
white again.

automatic-text-on-black-background.png

I downloaded LibO_3.3.2rc1_Linux_x86-64_install-deb_en-US.tar.gz and
installed it (with dpkg -i *.deb) on an up-to-date Ubuntu 11.04 (natty).
Then I ran "/opt/libreoffice/program/simpress text-on-black-
background.odp". The text "This text should be white!" has the color
"automatic" and is gray (see screenshot), but I expect it to be white.

I will remember that for the next time. The status is hidden by default
(-> Show Advanced Fields). I didn't change the status when I initial
filed the bug (default was NEW).

We urgently need some more information.

The color I see in your screenshot seems to be not grey, but grey 70%.
Can you please check and if necessary correct your report?

If you shut down LibO, rename your user profile (for WIN that's in
"AppData", I do not know the folder name for Linux), relaunch LibO, do
you still see that problem?

And yes, this default-status NEW is very worrying, but it seems that can
not be changed with the current Bugzilla version.

Note, my personal opinionns:

I don't think we need to worry about this NEW vs. UNCONFIRMED thing,
just ignore the difference. I doubt we want to use our resources on
making sure the Bugzilla Process is perfect. We don't neeed to try to
make it work exactly like OOo's bug workflow did; for instance, I don't
necesarily see that much value in having a strict difference between
CLOSED and RESOLVED. I much prefer just getting useful bug reports, and
somebody asking for more information when necessary, i.e. just what you
have been doing Rainer, thanks!

But others might disagree of course, maybe even some Document Foundation
steering group wants to eventually decide something, or maybe they have?

I see that problem in all applications. Example files and corresponding
screenshots attached for Writer and Draw.

The color is some kind of gray (not the Gray from the color pallet).
It's lighter than Gray 80% and darker than Gray 70% (see attached
screenshots).

Removing the user profile (deleting ~/.libreoffice) has no effect.

BTW, I updated LibO to the latest 3.3.2 RC2 version as you can see in
the screenshots.

Anything I forgot to provide or to test?

@Benjamin Drung:
Only one last question from Comment 4: problem only for DRAWing text boxes or also for standard text? (please delete keyword with your answer!).

Currently I do not have any more ideas what could be tested, and I'm afraid developers will not show interest before some more users will be affected. May be you can gamble with all settings referring to color, but I doubt that that will lead to anything useful.
May be you can publish your problem on an user mailing list, may be someone can contribute a good new idea.

As you can see in the black-background.odt, standard text is also
affected.

I made a very interesting discovery: Debian unstable (which ship a very
similar package of LibreOffice) is not affected. Then I discovered that
the color depends on the GNOME theme. 'Automatic' translates to white on
a black background for themes like Clearlocks and Skiki-Colors, but it
translates to "dark grey" for Ambiance (the default theme for Ubuntu
since 10.04) and Radiance.

Open your gtk theme (in /usr/share/themes/<name>/gtk-2.0/gtkrc on
Ubuntu) and search for ntext_color. Replace the following color with
FF0000 (red) for example and you will see that Libreoffice maps the
automatic color to red on all kinds (white and black) of backgrounds.

There are two issues here. The first is that LibreOffice doesn't
correctly handle cases where the GTK theme's text color is something
other than black or white. (See comment 14.) This is the case in
Ambiance, Ubuntu's default theme. Thus, all Ubuntu users are potentially
affected by this bug. This should be fixed to work correctly with all
arbitrary colors.

Additionally, there's the issue of what behavior is correct here. In my
opinion, LO should ignore the GTK theme entirely and default to black
text on a white background. Here's a use case to illustrate: When I
produce a document, the difference between the Ambiance default text
color (#3C3C3C) and black isn't readily apparent on the screen unless
the two colors are next to each other. (This probably explains why there
haven't been too many bug reports about this issue.) However, when I
print a document using auto colors on a black and white laser printer,
the printer dithers the text to create a dark gray. That makes the text
look messy.

Following the GTK theme is useful for situations where the content will
blend in with other content on the screen. But for Writer, what counts
is the paper and printer, not the on-screen appearance. And for Impress,
presentations are shown without reference to the current theme. In fact,
in general, a good GTK theme wouldn't make a good presentation theme,
just as a good GTK theme wouldn't be good for a printed document.

At the very least, please set the auto text color for light backgrounds
to black, without reference to the GTK theme.
