Update: I went from Ink Blue to Deepwood Green after feeding:

2x Plum (2 messages)
2x Pineapple (2 messages)
1 Valfruit (1 message)

I am still desperately trying to get to Grape Purple could someone PLEASE give me the formula because I read other people's things and really just confuse myself more.

I've gone through over like 10 colors and a lot of hours trying to inch my way to my color of choice.
