on gtk3 you can load a specific stylesheet that has 'application
priority'. that will overrule the theme.

something like this (copied from bluefish sourcecode):

GtkCssProvider *cssp = gtk_css_provider_new();
gtk_css_provider_load_from_data(cssp, my_css_string, -1, NULL);
stc = gtk_widget_get_style_context(GTK_WIDGET(btv));
gtk_style_context_add_provider(stc, GTK_STYLE_PROVIDER(cssp),
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
