Now, I managed to change the selection color from orange to
light gray which is very nice. But now I'd like to change the
text color of inactive/disabled menu items which are in black as
you can see "Available" "Away" and "Busy", the text is black.
I'd like it to be gray for example but I don't know how to
change the color of that text. Thanks!  share|improve this

change that property, you'll need to hack the gtkrc file for the
theme in question. I presume that you're working with Ambiance.
The first thing you probably want to due is make a local copy of
the theme instead of working on the system wide copy. Let's call
it Ambiance-Mod. Open a terminal an run this:  cp -r
/usr/share/themes/Ambiance ~/.themes/Ambiance-Mod  You also need
to edit the index.theme to use your new theme.  gedit
~/.themes/Ambiance-Mod/index.theme
