Chocobo Color Help

[Kaelah]

You might be better off resetting to desert yellow. You've fed so much fruit by now that a calculator won't be accurate since it won't know what your RGB values are at.
From desert yellow you will need: 1 × Valfruit, 6 × Plums, 10 × Berries
So in one feeding you should feed: 1 Valfruit, 2 Plums, 3 Berries, 2 Plumes, 3 Berries, 2 Plums, 4 Berries. (Or another pattern like this that spreads the larger numbers out.)

That should get you to Corpse Blue. :3 As long as at least the final fruit gives the feathers message you should hope to see Corpse blue come from it. Though you might see a few of the message, it depends how many colours you hop across on the way while feeding.
