Bisexual is someone who experiences romantic attraction, sexual attraction, or sexual behavior toward both males and females. A bisexual identity does not necessarily equatetoequal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual.
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). The key to understanding the symbolism of the bi pride flag is to know that the purple pixels of color blendunnoticeably into both the pinkand blue, just as in the 'real world,' where bi people blend unnoticeably into both the gay/lesbian and straight communities.
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 LGBTQ+ 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
