The usual colors are various shades of gray and white, sable and white, black and white, seal and white, red and white, or solid white.[2] There are a wide range of markings in the breed including face markings, blazes, a splash at the nape of the neck, and a collar or half collar. In terms of color variants, some Malamutes exhibit a dark grey to buff-colored undertone around their trimmings and white areas, presenting with a color-linked gene known as 'Agouti'. The eyes of the Alaskan Malamute are almond-shaped and are varied shades of brown; however, the darker eye is preferred. The physical build of the Malamute is compact and strong with substance, bone and snowshoe feet.
