The bisexual pride flag was designed by Michael Page in 1998 to give the community its own symbol, comparable to the gay pride flag of the mainstream LGBTQ+ community. The deep pink (or rose) stripe at the top of the flag represents same-gender attraction; the royal blue stripe at the bottom of the flag represents different-gender attraction. The stripes overlap in the central fifth of the flag to form a deep shade of lavender (or purple), representing attraction anywhere along the gender spectrum. Celebrate Bisexuality Day has been observed on September 23 by members of the bisexual community and its allies since 1999.
