 Lewis did note spotting patterns, saying, "... some of these horses are pided [pied] with large spots of white irregularly scattered and intermixed with the black brown bey or some other dark colour".By "pied", Lewis may have been referring to leopard-spotted patterns seen in the modern Appaloosa, though Lewis also noted that "much the larger portion are of a uniform colour".The Appaloosa Horse Club estimates that only about ten percent of the horses owned by the Nez Perce at the time were spotted.
