Compatible with iOS 7.x
Not only colorize iOS 7 UI, also randomize tint color *with blur supported* and with adjustable transition duration and delay! (Color Transition Animation)
Especially with folder icons, this tweak can keep their blur effect and tint enabled, or even override them with backdrop (Common iOS 7 blur effect).
This tweak just randomize color used by every UI, no colors selection included.
Configure from Settings.
