Biangles, 1985
The Biangles were possibly the first symbol for bisexual visibility. Within a couple years of its creation by Liz Nania, originally on pins, buttons, and t-shirts, it began to be adopted worldwide. Soon after the creation of the rainbow flag, the three colors of the Biangles became the basis in for the bisexual flag. The colors of the overlapping triangles represent attraction to both, or all, sexes, symbolized by pink and blue, traditionally associated with girls and boys in the US; and lavender represents the queerness of bisexuality, referencing the Lavender Menace in the 1970s and other cultural associations with lavender and queerness in the 1980s and 1990s. The triangle references the pink triangle adopted by LGBTQ+ communities in the 1980s in the US as a form of queer resistance, as it was originally used in Nazi Germany Germany in the 1930s and 40s to identify gay men.
