I just did quick napkin math assuming +/- 5 per fruit, and it looks to me like 1 Pineapple isn't enough, 2 Pineapples has a shot at getting there, and 3 Pineapples would be the best bet. 4 would be too many.

Obviously I'm really not sure at all, but I stuck with 2. I'm thinking its going to be kobold brown, soot black, or possibly deepwood or even marsh green. I really doubt it will be something aside from those 4 possibilities.
