The colourful Arica ceramic style was influenced by Tiwanaku culture (A.D. 500–1100) and lasted until just before the Hispanic period. This piece, from the Gentilar Phase, includes the so-called “Southern Tricolour,” a style found primarily in Southern Peru. In contrast, the monochromatic San Pedro style has no comparable styles in the region. The San Pedro ceramic tradition always included a range of decorative colours, including red, grey, black, reddish-purple and reddish–brown, but only one colour was used on each piece. This aesthetic feature appears to have been part of San Pedro cultural identity.
