Eclipse javadoc background color is black

My Eclipse javadoc view has a black background which makes it look terrible and partly unreadable (e.g. links are dark blue on black). Even worse, the javadoc popup has black background, too. I can't find the corresponding setting.

The answer by Sumit Singh showed me how to change the background for the javadoc view. However, I still see no way how to change the foreground. Even worse, the javadoc popup background color didn't change.

I don't think it's caused by a plugin, as it happens with a fresh install, too. This happens on Ubuntu 10.4. In Windows the colors can't be changed either, but there are fine.

Window > Preferences > General > Appearance > Colors And Fonts > Java
> Javadoc View Background  

You need to change the 'Tooltip' color in Ubuntu at the OS level.

None of the answers here worked for me (I have Eclipse Mars and Ubuntu 14.04). I had to edit /usr/share/themes/Ambiance/gtk-3.0/gtk-main.css. I've changed tooltip_bg_color to #f5f5bf# and tooltip_fg_color to #000000. After restarting eclipse, the change took effect.

As a KDE user you have to change the tooltip background color with systemssttings.
Navigate to

Application Apperearence -> Colors -> Colors

and adjust the Tooltip Background and Tooltip Text colors.

On ubuntu 12.10 (quantal) you can use the following two commands:

#foreground white => black
sudo sed -i s/tooltip_fg_color:#ffffff/tooltip_fg_color:#000000/g  /usr/share/themes/Ambiance/gtk-3.0/settings.ini /usr/share/themes/Ambiance/gtk-3.0/gtk.css /usr/share/themes/Ambiance/gtk-2.0/gtkrc
#background black => yellow
sudo sed -i s/tooltip_bg_color:#000000/tooltip_bg_color:#f5f5b5/g  /usr/share/themes/Ambiance/gtk-3.0/settings.ini /usr/share/themes/Ambiance/gtk-3.0/gtk.css /usr/share/themes/Ambiance/gtk-2.0/gtkrc

(Thanks to the other answers and this that helped me to figure this out)

Install the "GNOME Color Chooser" in Ubuntu (worked also on Xubuntu)

There you can set the Tooltip colors under the tab "Specific"

Had same issue with Neon on Ubuntu 16.04 Mate edition.

To fix it, I have created a small, user-specific GTK3 CSS settings file. It is stored as you HOMEDIR/.config/gtk-3.0/gtk.css

In my case, I compressed the spacing a bit, specified default font and also, set the appearance for the tooltip windows:

#####################
* {
    padding: 1px;
    font: Liberation Mono 12;
}

GtkToolbar {
    padding: 2px;
}

GtkMenuBar {
    padding: 2px;
}

GtkMenuItem {
    padding: 2px 6px;
}

.tooltip {
    background-color: #CAE1FF;
    color: #EEEEEE;
    text-shadow: none;
}
#########################

Please note, this issue has been resolved in Eclipse as of 8th November 2016. To have this fixed, please download one of the latest integration builds: http://download.eclipse.org/eclipse/downloads/
(The maintenance builds don't have the patch at the time of writing 2016-11Nov-09Wed).

I wrote a patch that introduced a new preference in Eclipse "Information Background/Text" under General -> Appearance -> Colors and Fonts. This preference generates the correct color on Linux/Gtk (White background, black text).
See: Bug 505738 – Define a information hover color which JDT, CDT or others can use https://bugs.eclipse.org/bugs/show_bug.cgi?id=505738

Subsequently I made Javadoc colors inherit it's color from that preference. See:
Bug 501742 – Default Javadoc text and background color should use colors consistent with Java editor background/foreground. https://bugs.eclipse.org/bugs/show_bug.cgi?id=501742

As an added bonus, it also works on the Dark Theme:
Bug 505851 – [Dark Theme] Style the HOVER_ colors for the dark theme https://bugs.eclipse.org/bugs/show_bug.cgi?id=505851

Also try this sudo apt-get install libwebkitgtk-1.0-0 after I installed the lib the javadoc looks so much better

I think the answer here to have a properly formattet tooltip (at least for people who use ubuntu and want to have a nice hover tooltip) with html elements like links working is to install libwebkitgtk as it is used by eclipse to show javadoc. It is not preinstalled on e.g. Ubuntu and does not come with eclipse.. use:

sudo apt-get install libwebkitgtk-1.0-0

and restart eclipse to have good looking tooltips.

You can change the color in
Windows->Preferences->general->Appearance .
