Symphony Arctic is a combination of the polygenic symphony trait and the heterozygous incomplete dominant arctic mutation. This combination has a pale greyish white to sandy colouration with fine dark speckling across the scales and soft, muted saddles. Symphony's most distinctive feature is found on the back of the head, where the pattern extending from the head and neck resembles two symmetrical musical notes. The arctic mutation creates a higher concentration of melanin at the borders of the saddles and surrounds them with white lines.
