The bisexual flag, also called the bisexual pride flag, is a pride flag representing bisexuality, bisexual individuals and the bisexual community. According to Michael Page, the activist who created the flag based on a color palette designed by Liz Nania, the pink stripe represents attraction to the same sex, while the blue stripe represents attraction to the opposite sex. The purple stripe, the resulting "overlap" of the blue and pink stripes, represents attraction to both sexes.

Page designed the flag to increase the visibility of bisexuals among society as a whole and within the LGBTQ community. He aimed to give the bisexual community a symbol that is comparable to the rainbow flag for the greater LGBT community. The first bisexual pride flag was unveiled at the BiCafe's first anniversary party on December 5, 1998. Wikipedia
