Why those colors and the different sizes? Before Page created the flag, the bisexual community often used a triple triangle motif called Biangles. It's two overlapping triangles, one pink and one blue, that create a smaller purple triangle in the space where they meet. Page took colors and a concept that the community was already using and turned it into a flag.

In a history of the bi flag captured by the Internet Archive, Page explained, "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)."

What's the meaning of the intersex flag itself? In a post, Carpenter said that he stayed away from colors traditionally associated with specific genders, like blue or pink. Both yellow and purple have been regarded as intersex colors, he explained.

As for the circle, Carpenter stated, "The circle is unbroken and unornamented, symbolizing wholeness and completeness, and our potentialities. We are still fighting for bodily autonomy and genital integrity, and this symbolizes the right to be who and how we want to be."
