Try ordering a "color kit" from that site too. I think they're about $5 and they show you the actual color of the paper and ribbons. I was super picky about my colors being claret (not red!) and gold, and that was on of the reasons I made my own...because I knew for sure the color would match my bridesmaids dresses. I know, it sounds kind of corny, but color-coordination is so much fun!
Anyways, I didn't know they had these kit things (I just ordered one with my attendants' gifts, for fun...) and now I'm majorly regretting not checking it out earlier! Live and learn!
