Blue bearded dragon

OK i just got back from petsmart. I know everyones favorite story. Anyways my mom and sister went to go get rabbit and horse stuff while i looked at reptiles and i go over to the bearded dragons and one had all of his limbs blue. I didnt say anything all though im about to call them. I dont really have any experiance with bearded dragons so is it sick or whats wrong with it or is it just some kind of morph. Thanks.

Was the shop claiming it was a normal phase or some kind of morph? Blue legs on a bearded dragon doesn't sond normal to me, might be a circulation problem.:(

Was it kept on blue calci-sand by chance ? I have seen them blue in the past some of the cheap calcisand dyes will run when it gets when and "temp" make the animal a nice blue phase and I have seen people try to pawn them off like that at a reptile show

It had green reptile carpet and it was housed with like 5 others and they didnt have any blue on them.
