Five basic colors of Wu Xing and compound colors of them are used, and patterns are drawn under certain rules. It is found from most Korean palaces and temples. The purpose of this workshop is to understand danchong, try to regenerate some of its patterns using geometric constructions, and finally apply generated patterns to cover faces of Platonic solids.
