Gardening - Harvesting

[Tam_Hawkins]

EDIT: Theory from reddit:


Possibly means that using all 3 dark fruits gives a black chocobo, while using all 3 light ones gives a white chocobo.

in German it says the colour of your chocobo goes mor into the dirction of: red, faint blue, violett, green, blue and yellow. So I would assume that is right (seeing as the say that the colour goes int a direction and not just changes) the direct words are:
Ger: Wenn du deinen Chocobo mit dieser Frucht fütterst, wird sein Gefieder violetter.
Eng: If you feed your chocobo with this fruit it's feathers become morle violett(purple?)
But of course it could still be that it is a one step Change.
