I suspect that the color of the medallions reflect your "status" with Princess because mine showed red (i'm Ruby) and my husbands showed yellow (He's gold).
I know that you can pay extra and get custom ones made but I am cheap and I don't want to do that. I really don't want to walk around with my "status" showing either. I noticed in the example it was blue. Is that a color of the one of the status's? If not, is it possible to order one in plain blue?
