Final answer:
The pottery of the U.S. Southwest predominantly featured black-on-white designs by Ancestral Puebloans, red-on-buff by Hohokam, and black on orange by the Aztecs, using local clays and natural pigments.
Step-by-step explanation:
Most of the pottery of the U.S. Southwest is characterized by a distinctive use of colors and designs, reflecting the rich cultural heritage of Native American groups in the region. Ancestral Puebloan peoples produced black-on-white ceramics, incorporating natural pigments extracted from local materials. The Mogollon of the Mimbres Valley were known for their black-on-white pottery, featuring finely drawn geometric figures and wildlife. The Hohokam tribe preferred a red-on-buff design, using the natural resources of their environment. Additionally, the Aztecs are known for their 'black on orange' pottery, with orange slip painted with contrasting black designs. The blue and white pottery often found in the U.S. Southwest, although not the predominant style, emulated Asian porcelain but used local clay with different properties.
