That is exactly why I removed iOS 7 from my iPhone 5, and went back to iOS 6. iOS 7's icons look like they were designed for giggling, 13 year old girls. I could not stand looking at that home screen every day, it's just far too garish for me.
Too bad too, as the features and functionality in iOS 7 are great. But it also has to be visually comfortable, and it's just not for me. I'll sit tight with iOS 6, and wait for a new version of iOS that doesn't feel like someone dragging a cheese grater across my eyeballs.
