The name was suggested by Ginn's brother, artist Raymond Pettibon, who also designed the band's logo: a stylized black flag represented as four black bars. Pettibon stated "If a white flag means surrender, a black flag represents anarchy." Their new name was reminiscent of the anarchist symbol, the insecticide of the same name, and of the British heavy metal band Black Sabbath, one of Ginn's favorite bands. Ginn suggested that he was "comfortable with "all" the implications of the name." The band spray painted the simple, striking logo all over Los Angeles, attracting attention from both supporters and the Los Angeles Police Department. Pettibon also created much of their cover artwork.
