Chocobo Coloration Conundrum

I looked around for a comprehensive chocobo coloring guide and found this site:

I was going for slate grey which calls for "O'Ghomoro Berries x21, Xelphatol Apple x7, Mamook Pear x7". So I bought those fruit at a cost of 60k gil and shoved them down my bird's throat.

Then I went to bed, and when I got up... it wasn't slate grey but gloom purple.

How would I get from gloom purple to slate grey? I don't have a lot of resources - my highest job is only 38 BLM.

There's a random factor to this as each feed item will increase or decrease the color palette within a specific range. Your desired color is Slate Gray (94R,94G,94B) but you got Gloom Purple (74R,62G,89B). This means you need to feed more xelphatol apples and mamook pears. I can't say whether or not you need more O'ghomoro berries, although you may try to feed some if you ere towards brown.

It also relies on the starts growing new feathers messages procs... search the forums around there are quite a few threads about this some very good and very accurate.
