Axanthic - While albinism is the lack of all melanin or pigment color, Axanthics only lack red or yellow or both.  Axanthics are a recessive mutation that produces a snake that is varying shades of grey, black and brown. Although most “brown out” as an adult, there are some lines that hold their color more than others. Axanthics are a color mutation only and thus will have the varying patterns as a normal ball python.
