I wanted a more subtle gnome environment but found that most themes didn't quite match what I needed.
I have taken the Unity theme (available in gnome themes extras) kept the blended appearance but tweaked clearlooks settings to create more subtle buttons.
The panel has been modified to use a dark panel colour which contrasts nicely with the unified windows.
Finally the colours are Suse green and a grey panel background is included in the archive.

I haven't posted before so hopefully my modifications allow me to do so, original authors details remain in the gtkrc file
