The blue represents sexual attraction to the opposite sex only (straight) and the resultant overlap color purple represents sexual attraction to both sexes (bi). The pink color represents sexual attraction to the same sex only (gay and lesbian). Page described the meaning of the pink, purple, and blue colors: The two triangles overlap and form lavender, which represents, in Nania's words, 'the queerness of bisexuality', referencing the Lavender Menace and similar organizations associated with the color. The addition of a blue triangle contrasts the pink and represents the gender binary. The design of the biangles began with the pink triangle, a Nazi concentration camp badge that later became a symbol of gay liberation. The biangles were designed by artist Liz Nania as she co-organized a bisexual contingent for the Second National March on Washington for Lesbian and Gay Rights in 1987.
