How old is he and what is his diet like? Also when did he last moult if he isn't a baby?
I'm just asking because sometimes the feathers do get damaged from general wear and tear, particuarly baby parrots and "old" feathers which can make them look very scruffy until they next moult. Young birds also dont preen themselves as well as an older bird. Feather damage is also more likely in cages that are too small or overcrowded with toys etc.
Other things to consider are if you have noticed him paying more attention to the damaged areas, it may be that he is over preening or damaging the feathers himself by chewing. Is the damaged feathers localised to a small area? are there any signs of il health etc? How long has this been going on? Did it coincide with his hormonal behaviours?
Personally if you come to the conclusion he is overpreening or feather chewing then I would treat it as the same as a plucker and go straight to the vets as they reckon over 70% of plucking is related to health or nutrition issues rather than psychological issues and plucking or deliberate damage are pretty similar...
The fact you mention colour loss is interesting but something that I know nothing about.
In the meantime see if theres anything you can think of that might be stressing him, try to keep him occupied and ignore any chewing behaviours, agressive preening etc.
