Mine have blue bellies. I'll try to post a picture as soon as they shed. The unshed skin is brownish so it makes the iggy look green. However the skin under the shed is vivid turquoise or aqua, depending on their temps or mood. They are striking. Right now, however, they have parasites (the vet thinks it is the stress of the double moves, first to Petco and then to my house). She said, however, that she has never seen iggies this color.
