My path of progression is as follows, with the number of feather messages given per fruit fed:

Desert Yellow->Millioncorn Yellow (1/1 Xelphatol Apple)
Millioncorn Yellow->Pumpkin Orange (0/9 Xelphatol Apples, 1/1 O'Ghomoro Berry)
Pumpkin Orange->Sunset Orange (0/10 Xelphatol Apples, 1/1 O'Ghomoro Berry)
Sunset Orange-> ??? (0/10 Xelphatol Apples, 1/2 O'Ghomoro Berries)

I'm expecting Blood Red, given the previous results others have posted. I'm undecided between Dalamud, Rolanberry, and Wine Red currently as to what I want.
