The standard dark mink is, in reality, a mutation developed by crossing and selective breeding of the various geographical "races" of wild mink for the dark color. Dark mink usually are the same color over the entire body surface, but there is a greater concentration of pigment in some areas. As a result, the head, tail, and feet appear darker, and there is a dark dorsal stripe (also known as the "grutzen") extending down the back from head to tail. The eyes, nose, and claws are dark brown. Frequently there are white markings on the belly, chin, throat, and breast. The standard dark mink is the norm to which all mutations may be compared, and from which the other color phases have been developed.
