Addition to Joseph's Post on concentration camp badges
These prisoner category emblems were used from 1936 to 1942.
Triangles of various primary colors (grundfarben) were used to identify each category of "undesirable": red for political prisoners, green for criminals, blue for immigrants, purple for Jehovah's Witnesses, pink for homosexuals, black for anti-socials, brown for Gypsies, and yellow for Jews.
To these triangles other classifications were indicated with strips and dots.
Rückfällige: Recidivist or repeat offender, coloured strip above triangle.
Strafkomp: Merits special punishment; punishment battalion inmate, black dot in a white circle.
Fluchterverdächtiger: Likely absconder, red dot in a white circle.
Jüdische Rassesschänder: Jewish race defiler, sexual relations with an Arian female.
Rassesschänderin: Female race defiler.
