I got my desired color on the first shot. What I did in the case of fruits like that, I mixed the low number of fruits(the plums) into the others evenly. So I alternated pineapples and valfruits and tried to evenly disperse the plums through that. So 1 plum every 3 rotations or so.

The thing is that the fruits adjust a RGB scale and if you cap out on a color, the fruit is essentially being wasted, which is why they suggest you try and alternate them a good bit. That might help some if you evenly space things out more.
