So I've been messing about with dyeing a bit, and think I've pretty much got the system down. I didn't see anyone else posting the exact numbers for each fruit, but I have a hard time reading how the forums look right now so I might have missed it, if so, sorry.
The numbers for what each fruit does is as follows:
Zelphatol Apple       +5 Red, -5 Green, -5 Blue
Mamook Pear           -5 Red, +5 Green, -5 Blue
O'Ghomoro Berry     -5 Red, -5 Green, +5 Blue
Doman Plum            -5 Red, +5 Green, +5 Blue
Valfruit                   +5 Red, -5 Green, +5 Blue
Cieldalaes Pineapple +5 Red, +5 Green, -5 Blue
There is no RNG involved whatsoever, you just need to push it as close as possible to your desired values to round it off to the one you want. Any colour can be done in a single feeding session, but thats more expensive than doing it in multiple (though at current prices still fairly cheap).
The one thing you do need to be wary of is order of feeding. Especially when working with colours close to the edges of the scale (Soot Black, Snow White, and so forth), and feeding a lot of fruit at once. The numbers on any colour cap at 255 max, and I am not entirely sure on bottom cap but I will assume it is 0. If you cap on either value then you will end up throwing numbers off, creating what has been interpreted by many as the element of RNG in the colour process.
My recommendation for that is to rotate which fruit you feed, which will in most cases avoid capping a colour accidentaly in the process.
So far managed on the basis of this to hit Shadow Blue, Soot Black, Colibri Pink and Snow White in one feeding session each, so seems to be holding up.
