What color hair did Montezuma have?

The Aztec Emperor Motecuhzoma Xocoyotzin (known today as Montezuma II) was typical of the native people of the Americas in having tan-colour skin, brown eyes and black hair. The first-hand account written by Bernal Diaz de Castillo also states that his skin was not particularly dark and he had a small black beard, which is less typical of native Americans since facial hair is generally very sparse.
