Well I tried this exact combination and feeding with all the same feather "proc" messages and ended up with a snow white bird....Too bad I was going for Lilac Pink.

Got a Seafog Blue chocobo, after feeding 20 O'ghomoro Berries and 8 Mamook Pears.
The first 2 didn't give me any message, then all of the others did. Also, I gave 3 o'ghomoro>1 mamook>2 o'ghomoro>1 mamook, if you want to know the order.

I would have taken a better photo, but it was already close to night time. :(

Got it.
I don't quite remember how I got from blood red to loam bown, but after getting Loam Brown feed it 2 berries, 1 Pear to Deepwood green.
From deepwood green, 1 Valfruit to soot black.
What do I have to do to get from Colibri Pink/Lavender Purple to Iris Purple? ;_;
Been going back and forth between those two colors even though I'm always feeding diffrent amounts of fruits or diffrent fruits in general >.<'
11 Berries, 10 Apples and 11 Pears got me Halatali Yellow
26 Berries and 22 Apples and Pears got me Orchard Brown
31 Berries and 30 Apples and Pears got me Wine Red.
These numbers are cumulative over three feedings and start from the chocobo's base color.
