Need help with System Colours...

[karinatwork]

I own a HTC S710 (love it!) with WM6, and I have created a today screen that for me is pretty much the perfect screen (and I am not going to change that). But I would like to change the colours from time to time. Is there a way to change the top and bottom bar and the other system colours in some way?

Thanks for any help!
