I have succesfully changed the bg colour of some buttons in my program by the use of styles. But..

As soon as my beautiful greenish colour has been painted onto the buttons, my default pixmap theme paints it over with it's gradient grey.

How do I stop this?!

I know I can stop it by choosing a different engine (like notif), but I want to use the default engine... See the prob?
