The smear of murky tones across the lower-right half of the iOS 6 grid is replaced with whites and a few light blues on iOS 7. Similarly, iOS 6’s handful of different visual styles (and several eccentric outliers) have become essentially two main themes on iOS 7: the paper-like, bright style in about 75% of apps, and the dark utility style for the remainder.

A great piece by Matt, especially in his thoughts on “flatness” and “brightening”. The pixelated screenshot comparison shows just how striking the difference between iOS 6 and iOS 7 is.
