After looking at that snake several times, I think it looks like a hypo Opal. Don Soderberg's hypo snows are called corals because of the effect of hypo on the coloration. Given the freaky ways that lavander and anery A interact, it may be that hypo has a similar effect on an opal. Anyway, it's just a thought . . . actually, just a stab in the dark!
Beauty, though!
