Permafrost is a combination of the recessive sable mutation, the recessive caramel mutation and the recessive evan's hypo mutation. The background colours can be described as a sandlike colour with a contrast of orange red to greenish blue. Almost like oxidised copper. The saddles are significantly darker than the background colour. The sable mutation creates a high amount of iridescence. Iridophores are responsible for the reflective qualities and hues.
