I beleive it is a Pastel Hypo, and I also know that some green hypo's are compatible with orange hypo's. I know because we bred a green hypo to a het orange hypo and got 5 hypos, 3 orange, 2 green. So if you felt like proving it out, I would try an orange hypo if need be, or look for a green one(they are defiantely better looking as adults, the male at work is one of the most stunning bp's there). Again I'm pretty sure its a straight up hypo pastel, not het, but breed it to find out for sure. Regardless he's gorgeous, and a great pick! Congrats, and good luck. ~Caylan.s.~
