Ink Blue.

I basically winged it using 36 apples, 36 pears, 36 berries over 3 feedings. I would go apple, pear, apple, pear, apple, pear, then some berries until I got a couple feather change messages and repeat this until I would use a 3rd for each feeding.

I went through 3 different shades of darkening brown and finally used 3 berries and 1 pear on my 4th feeding to get to Ink Blue.
