Tonto Basin polychrome ceramics encompass three distinct styles of red, white, and black painted pottery. Manufacture of the earliest Salado polychrome ware - Pinto Polychrome and Pinto Black-on-Red - began around A.D. 1275, during the Roosevelt Phase. Gila and Tonto polychromes developed later, appearing early in the 1300s, during the Gila Phase (Simon 1996).
