Does anybody know how to change Skype chat text color? It use a config which is looks like themename/gtk-2.0/gtkrc and there is a line which set this color to DefaultTextColor. But there is no line which set this DefaultTextColor (I mean something like "DefaultTextColor = "#ffffff"")
This problem is the same as problem with built-in chat app, but in last one we can change color in settings but in skype we can't.
