Pretty clearly fits the challenge. I like the colors, I also like the fact that the excluded candy doesn't match any of the others shown. Lighting looks good as does focus. 7
I like your choice in pairing each of the other candies. It really adds to the loneliness of the outcast much more than a homogenous group of candies would have. I have somewhat mixed fealing about the white background though. On one hand, it provides nice contrast, but it may be a bit overpowering as well. Hopefully someone with more experience can offer a better comment about that.
