How to get the black theme of unity 4.2 back?

I am using unity 4.2 and i liked the black theme of the version so please tell me how to get it back i don’t like working in grey colored interface.Please help me.

If you have pro, Edit->Preference->General->Skin
No pro, no black.

Were you on Pro trial?

You can download a this nifty little utility:

Then place a black image over your Unity Screen and adjust Opacity and Select ‘Click Through’

With this you won’t get exactly the same results as having a Unity Pro Dark Theme but you can lower
the brightness quite a bit so it’s easier on the eyes.

Hope this helps.
