You might remember Lydia and David's artsy New York wedding because of the bride's incredible technicolor gradient dress, but that wasn't the only awesome colorful detail that we crushed on...

Instead of asking guests to sign a traditional guestbook, each person at the wedding picked a character to color (which included rabbits, cats, and robots) and wrote a brief message to the couple next to their chosen avatar.

You can see the photo in even more detail right over here. And then you can check out more "colorful" guestbook ideas over here!
