you may be very right, and it's just a killer variation, but here's where the confusion plays in.
Sulphur Snow as far as i know has BHB-Anery bred into it. so it's Lavender-Anery (Sulphur phenotype)
This Anery-Snow was bred to an Axanthic [i didn't see the rest of the clutch because the breeder said he messed up a little, and they didn't make it. this was the lone survivor. but he did say from the few eggs (4-6, can't recall how many) they all were axanthic!] knowing axanthic and anery are not the same, we shouldn't get axanthics in the 1st place. so i guess the sulphur snow is het Axanthic. i have no clue whether the axanthic female used is het for anything. all i know is she's from Jeff Lecompte's stock. the light areas on this "axanthic" are really pinkish, not purple like on the axanthic, yet not blue-grayish-silver like on the ghost
I'm sort-a leaning towards it's what an Axanthic-Anery 2x Homozygous specimen would look like. but i'll know more after i breed her back to the sulphur snow.
