Tough choice. I have it narrowed down to yellow, green, pink or black, but it's pretty difficult to choose after that. If you pinned me down though, right now I'd probably pick black. It would be pretty handy in making choices and buying stocks would be easy.
I think I'd pick one @ random and consume it on the blind then try to guess what my powers might be, of course I wouldn't be jumping off any rooftops or lining up as nose tackle in the NFL right off the get go.......
