Where can I change the background colour of the kitchen sink info?

[Alex]

As the title really, I can change the background around the avatar and the background for the username/title, but I can't for the life of me find where to change the background colour of the extra user info.

Have tried firebug (as that's what i usually use) but still can't figure it out, anyone know?

Thanks

And so i did.
