Is iOS 7 designed for white devices?

So I've not gotten iOS 7 onto my black iPhone 5 yet to try out but early indications from reading around seem to show that iOS 7 is more suited to the white iPhone. Also the marketing that's been put out so far by Apple would seem to point in this direction, there are very few shots of iOS 7 on the black iPhone.

We're meant to be seeing much greater synergy between the hardware and software due to Ive's involvement so I'm thinking that this could be a hint towards the next iPhone design. It looks absolutely great on the iPod touch hardware and I'm thinking that come September/October we may be in for a refresh that sees the iPhone departing from its traditional black/white and moving towards white with various colour options.
