Using the Chocobo colour calculator I finally got Cactuar green! Thankoo so much.
I had been looping Celeste > Apple > Celeste > Apple for ages, wasted so much fruit. From Apple it said to use 8 apples, 9 pears and 11 berries. I used 4 apples, 4 pears, 5 berries, 4 apples, 4 pears, 6 berries. (I forgot to use the 9th pear.) Got quite a few feather messages along the way but just fed the lot anyway. I'll post a pic later.
