Hmm, I wouldn't be fond of that idea, Nelly already did it.
I hope that -WHITE- has a cover that is reminiscent of a picture from July 2006's SCawaii.

As for -BLACK-, I don't really have any clues, but I'm sure whatever Ayumi comes up with, it will be very elaborate. No, not the picture, but the emotions portrayed etc.
