Harlequin is the term used to describe the color patter found on dalmatians
and some great danes. When you start looking at what causes the patterns
on the genetic level you find that it is not actually black spots on
a white field but a white field with holes where black shows through. Although
not officially recognized by the AKC great danes can also come in a related
color known as fawnequin, which is tan spots instead of black.
