Sunset Superarctic Anaconda is a combination of the recessive sable mutation, the recessive pink pastel albino mutation, the homozygous incomplete dominant superarctic mutation and the heterozygous incomplete dominant anaconda mutation. They are born with a fluorescent pink colour. As the snake ages, the colouration darkens to a dusky lilac to mauve, and the saddles become darker and more visible than in young animals. The eyes are dark red. The anaconda mutation reduces the dorsal pattern.
