Ok, your contest is just way too much fun for me. I really enjoy working on these different ideas.
So, here is my concept of the falling paper you were talking about. i used all 4 of the colors because I think they balance each other out. None of the colors really dominate another one. The yellow paper has a curl on one corner which adds just a slight amount of orange in there. Let me know what you think of this idea. I really think it works well!
