The pink triangle (German: Rosa Winkel) was one of the Nazi concentration camp badges, used by the Nazis to identify male prisoners in concentration camps who were sent there because of their homosexuality. Prior to World War II, pink was historically a male colour as an offshoot of red, and pink was chosen not because it meant the wearer was feminine, but because they liked other men. Every prisoner had to wear a triangle on his or her jacket, the color of which was to categorize him or her according "to his kind." Jews had to wear the yellow badge (in addition to any other badge representing other reasons for incarceration), and "anti-social individuals" (which included vagrants and "work shy" individuals) the black triangle.
