When you say "pressed", you mean active? I think you need to look up the documentation on styles and themes.

So if you want to affect the appearance of the button while "pressed", which is called "ACTIVE", then why are you setting its colour in the "NORMAL" and "PRELIGHT" states?

If I understand your intentions right, I don't think you need signal handlers or call-backs. Just set the widget's "ACTIVE" background colour and GTK will do the rest.
