The picture is out of focus so I'm having a hard time seeing. He's at least a leatherback. With the fussy picture, he also looks like he could be a silkback.
He does have a lot of red. Was he sold to you as a "red leatherback"? If he has red parents, it is possible that he could get more red with each shed. But the really red ones are very red as babies, too.
Do you have a better picture? One that's not out of focus and brighter, preferably natural light.
