Toffeebelly Shadow Arctic is a combination of the recessive toffeebelly mutation, the polygenic shadow trait and the heterozygous incomplete dominant arctic mutation. This combination has a light gold-brownish colour. Often there are a lot more shades in a clutch. These colours vary from green, red, orange and yellow shades. Head pattern and other blotches have black edges giving it a shadow appearance. Some have an eyebrow above the eyes. The arctic mutation will lighten the snake up as it ages and gives the borders a higher concentration of melanin.
