The magenta (pink) stripe at the top of the flag represents sexual attraction to the same sex only (gay and lesbian); the royal blue stripe at the bottom of the flag represents sexual attraction to the opposite sex only (heterosexual); the stripes overlap in the central fifth of the flag to form a deep shade of lavender (purple), which represents sexual attraction to both sexes (bisexual). The flag's aspect ratio is not fixed but 3:2 and 5:3 are often used, in common with many other flags.
