Wondering About The Colouring of my Blue Crowned Conure??

I am looking for some help in regards to my Blue Crowned Conure. I have looked up several sites and have noticed that the pictures of the birds have no markings on the top part of their wings...mine does redish orange and now some yellow is appearing...he also from about the tummy down is changing to a much lighter green. Is he a mix? If so with what? IF anyone can give me some info on this or direct me to someone who can tell me it would be greatly appreciated. Thank You. http://PetoftheDay.com/talk/smile.gif
