Inconsistent Colour Scheme

Dunno if it's bugging anyone else, but the more screenshots of iOS6 I see, the more it annoyed me that the colours seem all over the place. I'd be happy to see them go grey to match the iPad, or stick with blue, or just be consistent. But from what I've seen there's grey, black, white, and still blue. And sometimes the status bar is blue too randomly?

Anyway, just my thoughts, and it's probably just my OCD kicking in here
