 I played with it a lot - and I should say it's nearly impossible to do what
you want if you use pixmap-based engine. Even if you don't change any color in
the style, the engine won't be used after you set_style on that widget (or you
have to GTK_WIDGET_SET_FLAGS (w, GTK_RC_STYLE); to engage theme again, but
then the colors you've changed won't be used). Even doing that hack in
"state-changed" signal (setting/unsetting that flag for different
values of GTK_WIDGET_STATE(w)) doesn't work as expected (yes, I tried it, but
didn't find working solution).

 If your GUI design guidelines force you to make the button very
distinguishable from other, you can resort to sticking fancy pixmap on that
button.
