German-languageschematic chart on poster showing cloth insignia worn on prisoner's uniforms in Nazi concentration camps before and during the early stages of World War II in concentration camps with a more elaborate triangle-based badge coding system. Double-triangle badges resembled two superimposed triangles forming a Star of David, a Jewish symbol. In addition to color-coding, non-German prisoners were marked by the first letter of the German name for their home country or ethnic group.
