What colors go with iphone 5s gold?

I'm planning to buy iPhone 5s gold. I want to buy Michael Kors phone wallet with it. There are a lot of colors (black, light pink, blue, red, grey, yellow, etc. ).
I don't know what to buy.
Mainly I want a wallet that goes with everything I wear & compliment my gold iPhone color.
Any thoughts?

I think simple colours like white and black and of course gold! Oh and btw michael kors does the nicest 5/5s cases ever!
