I have 3 Parrots my parrots color faded from they dye but their natural color seems to be a bright orange now. I think it depends on the parrot weather its stressing or not and also what you feed it. I've had a huge parrot that got to big but that thing was a bright redish orange. I've also had a semi-big faded orange parrot. I noticed when I changed the food they got brighter.
Sorry guys, can't get pics until i get my hands on a better camera. All the pictures that i take come out blue. Thanks for all the help though everybody!
