I tried to dye her Colibri Pink with the 7x Doman, 8x Val and ended up getting Rose Pink.
I think that what matters is not how many fruit you feed it of one type, but how many times you get the "growing new feathers" message with each type of fruit.
I think she's beautiful though, what do you think? If anyone attempts for Colibri Pink, could you count how many times you get the feathers message with the Doman and Val and report back here? Although I love this color, I wouldn't mind a more vibrant pink.
