Green and purple are a good color match. Of course if you want to get into the full tertiary you could add some orange to round things out but I think this is looking pretty nice. Do you care? No? Either do I. Just eat it!
Brownies are pretty exciting on their own, then you put them on a stick and everybody gets all jazzed, then you dip them in colored candy and it gets kind of swoony in here and THEN you come out with all sorts of sprinkles and I'm pretty certain we've lost several to a case of the vapors.
