LibreOffice Productivity Suite

Comment 3 for bug 734428

Open the gtk theme (/usr/share/themes/Ambiance/gtk-2.0/gtkrc) and search for ntext_color. Replace the color (3C3C3C) 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.
