Chocobo Dye - The Missing Manual

[Giantbane]

especially if SE doesn't have a fixed range for all the colors (more RNG? LMAO).

I highly doubt the range is random. Possible, yes, but it's sort of a silly way to build it so I'm going to go out on a limb and say this isn't what they're doing unless we find some strong evidence to the contrary.

There's probably a single algorithm that converts from RGB > dye. The ranges would be dictated by that algorithm (whatever it may be).
