	I've used the gnome-tweak-tool for this (in my case to get rid of the yucky 
sans-serif fonts).  On the Appearance tab there's an option called Global 
Dark Theme.  Also, in Firefox,  I've installed a theme called Compact Dark, 
which helps, too.  There are numerous other dark themes for Firefox, and 
probably for Chrome and Opera, too.
