The "White Snake" gene complex is the stunning homozygous form of the Platinum gene.  There are 2 strains (Leucistic and Ultra Ivory) which are located on the same allele, which work similarly to the Albinos.  These strains crossed together make an intermediate form, called an Ivory.  Stark white snakes with solid black eyes (which are actually very dark blue with red pupils), all three phases have an almost mythical appearance.  Leucistics are born and stay solid white; Ivories are born off white, with small amounts of yellow patches and grey scale tipping, then grow into bright white adults with minimal pattern; and Ultra Ivories display a radical blend of bright yellows, oranges, and thin black accents that intensify with age.
