Pastel Frostbite is a combination of the polygenic pastel trait, the recessive axanthic mutation and the recessive caramel mutation. Frostbite, also referred to as Meltdown, is the combination of axanthic and caramel. This combination has a grey to silver colour with a dark grey pattern and some slight blue hues. The caramel mutation removes some of the head pattern. Pastel is a polygenic enhancer trait that draws out more colours.
