How do I change the basic program background colour?

Any ideas on how to tweak the colour of the menu background of W7 applications?

To be specific - as I'm not sure of the correct name - I'm talking about the pale blue colour which appears behind "File Edit View History " on Firefox (and other programs), below the title header. It is used as the unselected tab background too.

I don't like it!

I want this colour to appear uniformly grey, as in XP, and without the light slim horizontal embellishment cutting through the words.

Thanks!

Hmm, thanks, that will probably work.

Not sure why you can't alter this natively in W7. I wonder why you can't alter the system fonts easily too... or add and change program icons (I use Open Office and prefer a big green X to their Excel icon, and a a big blue W to their word processor icon).

Thanks for the tip though.
