Update 3/12/2012:Thanks to nowerries for telling me how to fix Ubuntu Software Center. I'm trying to figure out a way to apply this fix to my dark themes but until then use this fix.
Only bug I have noticed so far is fonts unreadable in Ubunut Software Center the fix for this is to in terminal type...
sudo gedit /usr/share/software-center/ui/gtk3/css/softwarecenter.css
.... and change the color value of @define-color super-light-aubergine to #363636.
Updated 1/19/2010: Fixed Evolution not displaying html messages correctly. Also changed the name it is more of a brown then black
Okay People's per requests:
Here is a Black n Grey GTK with Unity support (I think but don't run Uniy so let me know). This is my Black n Green GTK theme with Grey added instead of the greenish color. I may do some other colors
