do something like this, and was only able to that with modifying 
gtk2-engine source in:
--- a/engines/clearlooks/src/clearlooks_draw_gummy.c
+++ b/engines/clearlooks/src/clearlooks_draw_gummy.c
@@ -1199,13 +1199,30 @@ clearlooks_gummy_draw_list_view_header (cairo_t 
                       *cr,

That of course depends on what engine you use.
