Chocobo Color Help

[Icefall]

I'm at the near end of my sanity here. I've been trying on and off for weeks now to get my chocobo to Corpse Blue, but it seems to be stuck in a cycle of Sky Blue, Celeste Green, or Apple Green. I've tried the color charts, I've tried a few different calculators. I've tried micro feeding. I'm about out of some fruits and I feel bad for wasting so much of my FC's resources. I've tried asking for help on relevant topics before, but no one responded.

Please, can someone help me get out of this loop and to the color I want? I'm currently back on Celeste Green. Thank you so much for your time and help.

You might want to try feeding berries till first "New feathers" message. Unfortunately colour map only got Corpse blue + pineapple = Celeste green path, but the opposite fruit might work. If you get Sky blue, you might want to use berries to get Raptor blue and then use pineapple to get Seafog blue -> Corpse blue. Colour map only helps if you use single proc method.

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.
