What are some good wedding color ideas for a fairy tale themed wedding?

At first I wanted royal blue and teal but then I started shopping for favors and invites and I'm having a hard time finding those colors. Also, I want my bridesmaids to look good and they aren't too keen on the idea of wearing teal. They like the royal blue though. I'm into cool colors like purples, blues, and greens. My favorite colors are baby blue, sea green and teal. Any suggestions are welcome. I thought about going with pastels like baby pink, purple and blue but then my sister griped at me that she doesn't want to wear anything pink. I told her she probably wouldn't but she wouldn't listen. Urgh! 14 year olds!!!
