Earring Display Cards Help From All The Stampers Out There!?

Help from all the Stampers out there!? - earring display cards

I make jewelry and I make my own cards can demonstrate to pending sales. I intend to a black card to use as the best of my jewelry. My question is: I have a car Stamper ink on my logo on the upper slope of each card to print. Is there a color that is very much against the black card? Also if anyone knows of any sites that great ideas for displaying jewelry I like you "have joined". Thanks in advance!
