Wedding favors help!?

I'm getting married in Sept, and my colors are brown and tiffany blue. For favors, I was thinking those tiny tiffany blue favor boxes with pastel melty mints in them tied with a white bow. Yay or nay? And I was wondering what favors are the best, and which favors (as a guest or otherwise) you have HATED, or seriously disliked lol Thanks guys!
