Comment 2 for bug 204053

Does anyone know if there's a standard GTK style for this? I'm not sure I feel good about hardcoding the colour; I can well imagine that that might interact badly with things like high- or low-contrast themes for users with different kinds of visual impairment.

http://library.gnome.org/devel/hig-book/stable/design-color.html.en is relevant here.
