I haven't tried them but heard that Reynolds makes great cupcake papers in many different colors and patterns that hold their colors well. I usually use a heavy black paper that I get from a local cake supply. 
you can find them on the Reynolds web site. They say they are available in stores like Target but I have never seen them.
I recently found some at my regular grocery store made by Reynolds. They are foil on the inside and paper on the outside. They came in a few different designs. They call them StayBrite baking cups. I'm sure there are other options, but this is what I have found so far.
Here's a pic of some that I used:

Good luck!
Thanks for the info on these cups! I found them online at Amazon, but you have to buy a case and there are only 4 patterns available. If you go to www.cupcakecentral.com, that's apparently Reynolds cupcake website, and you can order online there. Lots of cute ideas on that website too. Can't wait to use these!
Look for GREASEPROOF Liners. They hold their shape and color. I purchase mine from www.gloabalsugararts.com and www.countrykitchensa.com They now come in great colors and prints. Top Quality!
