After 1939, concentration camp prisoners were divided into categories according to each individual’s status as a prisoner, each of which was represented by a differently colored inverted triangle: criminals were labeled with green inverted triangles; political prisoners including Romas, nonconformists, vagrants, and other groups were labeled with red or brown triangles; homosexuals were labeled with pink triangles; Jehovah’s Witnesses were labeled with purple triangles. Non-German prisoners had the first letter of the German name for their home country sewn onto their badge. The two triangles forming the Jewish star badge would both be yellow unless the Jewish prisoner was included in one of the other prisoner categories. For example, a Jewish political prisoner was identified with a yellow triangle beneath a red triangle.
