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.
Design and colors 
Page took the colours from an existing bisexual symbol and gave it his own spin, saying,
||In designing the Bi Pride Flag, I selected the colors and overlap pattern of the 'bi angles' symbol.
The deep pink or rose stripe at the top of the flag represents the possibility of same gender attraction; the royal blue stripe at the bottom of the flag represents the possibility of opposite gender attraction and the stripes overlap in the central fifth of the flag to form a deep shade of lavender or purple, which represents the possibility of attraction anywhere along the entire gender spectrum.
The flag's aspect ratio is not fixed but 2:3 and 3:5 are often used, in common with many other flags.
The exact colors given by the designer are: PMS 226, 258, and 286. (approximate HTML/RGB values: #D60270, #9B4F96, #0038A8)
