Critique of iOS 7's design on the iOS 7 forum isn't thread worthy?
I agree that the icons lack consistency. I think it'd look better if they could tone down the neon colors and and more warmth to some of the icons. Right now there's a lot of clashing going on in the apple icons. This negatively affects the control center area as well. When it's open on the home screen, the neon icons bleed through quite severely and distract from the interface. There's too much going on in the UI for the control center, I hope Apple takes another look at it. A higher opacity, or even inverting the colors to use a dark background with white buttons/text, would look better IMHO.
