That should happen by default, check if it isn't your theme's fault.
Guaranteed to work correctly are at least Default and Mist themes, and
one I know that has issues with colors is Gonxical. There are many
slightly broken themes out there however, so always check with default
theme and one other well-supported theme when you encouter problems like
that. Saves lots of time and queries in many cases ;). Also, watch out
for theme-induced performance problems, for example pixmap is known to
be slower by factor of 3-10 than Default theme.
