The bisexual pride flag was designed by Michael Page in 1998 in order to give the bisexual community its own symbol comparable to the gay pride flag of the larger LGBT community. His aim was to increase the visibility of bisexuals, both among society as a whole and within the LGBT community. The first bisexual pride flag was unveiled at the BiCafe’s first anniversary party on December 5, 1998 after Page was inspired by his work with BiNet USA.
Page describes the meaning of the pink, lavender, and blue (ratio 2:1:2) flag as this:“The pink color represents sexual attraction to the same sex only (gay and lesbian), The blue represents sexual attraction to the opposite sex only (straight) and the resultant overlap color purple represents sexual attraction to both sexes (bi).”
Page describes the flags meaning in deeper terms, stating“The key to understanding the symbolism of the bi pride flag is to know that the purple pixels of color blend unnoticeably into both the pink and blue, just as in the ‘real world,’ where bi people blend unnoticeably into both the gay/lesbian and straight communities.”
