Can't go wrong with black, but I do like colored cases. I'm using a vivid hot pink/black Spigen bumper my 5s right now.Man...I always want to be the guy that puts a cool color on his iPad...however, I ALWAYS revert back to understated black/black carbon fiber. My wife won't let me get anything else now because I always end up back with black.
On second thought, I might go with a beige Apple Smart Case. It looks like the Invellops case was made for the 1st generation mini and it covers the noise canceling mic on the back. I'm not sure how much of a problem that would be. I can't decide because it looks like the Apple case doesn't have magnets on the back to hold the front cover in place during use, whereas the Invellops does.
