Coffee and Milk
In my opinion it's time to pass on that screaming orange. I suggest using light brown colors for an distinctive yet modern look.
It uses the Murrine Engine and Emerald but there should also be a matching Metacity theme.
This is the current working state, I intend to post the GTK and Emerald theme soon.
