The pics are 'peach tone' or something. The dragon, the floor, the background, etc. is all peach....
Judging from those pics it just looks like either stains, or just a slight yellow-green tint that somehow shows a bit in the 'peach' tone of the pics.
:-/ From the first posts it sounded like your dragon had alot of bright teal/turqiouse in him (like the coloring of the water dragon I posted)... not just some hints of yellowy-greenish.
But generally his colors look like a 'normal'. But get better pics... like said already, take the pics outside they come out better too.
*edit*
Just looked back at the pics... in the first pic, The little bit of yellowy speckling thats on the dragons, I also see it on the floor and even the cabinets... Looks almost like just the peach-toned camera registers some areas as a yellowy-green color that arent even there.
