The artistic process of coloring concrete was showcased in Denver in the spring of 1995, as the city installed a unique multicolored concrete intersection to demonstrate the environmental advantages of concrete pavements.
Called the Champa Tapestry, the intersection was designed to reflect the area's Arapaho cultural heritage. The project used three primary concrete coloring techniques: application of a dry-shake hardener, integral coloring, and staining. Before the concrete set for each of the first two coloring phases, workers pressed various rubber molds and wire stamps into the concrete surface to form leaves and other shapes. Stains were later applied to these shapes.
