Results from my 6th feeding came in. I found a definite way to Dalamud Red.
From Blood Red, O'Ghomoro Berries fed until 1 "New Feathers" message yielded Dalamud Red for me.
I will start my 7th feeding soon using only pears. Want to enjoy my Dalamud Red for a bit since this is what I'll most likely settle on eventually.
Old Post with all my feedings Here.
Edit. Well.. that's actually 40 apples with no message then berries till 1 message; but I'm fairly sure it would work from flat Blood Red. I'll confirm it eventually if no one else does because I will be coming back to Dalamud Red.
And I may stick with Berries for now.. thinking about capping each deepen fruit then move to the next.
