Here's a little number I whipped up a while ago - I was going for a kind of comic book feel, hence the word bubble sentiment and the black line border around the image (which I did with a straightedge and black marker). I forgot to snap a pic of the inside, but it said "Hope it was SUPER!"
I'm entering this in this month's Oozak Challenge, "Anything Goes with Your Favorite Colors." I love anything aquamarine, teal, turquoise, etc. If it's bright and it's got blue and some green in it, I'll love it! :) Purple, in general, comes in somewhere second to that color range.
