Golden fawn with a black mask is the most commonly seen color, but the breed standard recognizes five other colors and patterns: brindle (black chevron stripes on a gold background); glossy black; pure steel blue-gray; harlequin (a white base color with black torn patches distributed over the entire dog); and mantle (a solid black blanket extending over the body and a black head, with a white face blaze, neck collar, chest and white on the forelegs).
Merle is also a recognized color/pattern!
