Thanks for the quick reply!

re: "normalizing hue," I had my chocobo stuck going from Deepwood Green -> Marsh Green -> Deepwood Green. Today I fed it 1 Pineapple + 1 Valfruit to get it theoretically to soot black, but not feather proc happened. After reading this, I removed the chocobo, restabled, then fed 1 pineapple, then got the feather message.

I don't know if that necessarily proves or disproves the normalization thing, since it's also possible that the fruits are just RNG and didn't produce enough change the first time.
