technically she is an albino as she's a snow, which is a double homozygous recessive mutation.
In reptiles, albinism just removes melanin (= brown and black pigment) resulting in either white or pink in place where melanin once was. Other pigments within their skin's chromatophores are generally erythrins (= red and orange pigments) and xanthins (= yellow pigments) which cause albino, or as some call amelanistic ("a" means to lack, melanistic being melanin), animals to be brighter or to "clean up" red, orange, and yellow colorations. Albinism is a simple recessive mutation.
However, your Epic is also expressing another simple recessive mutation: anerythrism aka anerythristic aka Black Albino. Anerythristic animals lack the ability to produce erythin pigments (reds and oranges) typically resulting in gray on black or gray on brown animals. Nice examples typically have little to no yellow pigment showing along the chin and neck region, but generally this comes into color as the snake's skin cells sequester carotenoids.
The result of combining albinism with anerythrism is normal, or wild-type, colored offspring. Those offspring are carries of 1 copy of albinism and 1 copy of anerythrism, but since these traits are recessive again the offspring are normal (dominant color to albino or anery) in appearance. When those offspring, or even unrelated animals with the same genetics, are bred to one another, in theory via Mendel's dihybrid cross 1 out of every 16 babies should be a "snow" or an albino anerythristic.
Thus why she is technically a snow. Many people unaware of reptiles and other animals possessing skin pigments other than melanin come to think that any and all animals that are albino are always white. It is typically mammals that fall into the case of albinism equaling white coloration. Interestingly, most albino mammals wind up with yellowed hair. AND dependent upon the type of albinism, such as in humans, some can have white OR caramel colored skin, white, yellowed, or caramel colored hair, and oddly can have red, pink, blue, green, gray, OR brown colored eyes. Red eyes in the case of albinism is just simply the fact that the eye lack any melanin pigment, resulting in light reflecting off of blood vessels within the eye yielding the red or pink appearance.
