Second, I have great respect for Neven Mrgan as a designer. He’s an accomplished artisan and not to be trifled with. However, his post on how the design of iOS 7 icons is “wrong” is misguided and I feel the need to address why I think that is, because I often see designers get caught by this particular hobgoblin of consistency—that a design just “feels” right to them without offering any rational justification.

It’s interesting watching designers hammer this stuff out.
