The Balabac chevrotain is an overall dark-brown color, although each hair actually has three bands of color: a light base, an orange midsection, and a long black tip (this last section gives the chevrotain its dark appearance). The undersides are slightly lighter and the inner surfaces of the legs are white. The black throat is marked with three white stripes which extend down from the white chin. The head is usually darker brown than the rest of the body, with bright orange eyebrow stripes. The upper canine teeth are enlarged into little tusks.
