My first thought was a faded out Pastel - those markings are very pastel-ish. It has the "brown out line," where the alien heads are two-toned. The clean alien heads themselves have the soft, smooth look and altered shape seen in Pastels. The clear labial scales are a Pastel trait, and the irises are Pastel, too. (Everyone says Pastels have green eyes . . . while that seems to mostly hold for the youngsters, my adults have all had that orange highlight at the top of the iris.) So, good chance that it's the mix.
That color, could be a Pastel Axanthic. . . . But I don't know if the eye of a Pastel Axanthic would have that color or not, tbh. If the animal is under stress, that will fade them out, as well.
Desert (the old mutation no one works with because of the repro problems), though, will do similar things to the markings.
Like nikkubus said, we'd need a head pic to give better guesses.
