Outside of the binary
The Polysexual Flag was designed in 2012 by a Tumblr user named Samlin, to represent the Polysexual community.
Samlin deliberately designed the flag to incorporate three horizontal stripes, with magenta at the top and blue at the bottom, to be like the Bisexual and Pansexual flags. As with both of them, the magenta stripe represents femininity and blue represents masculinity. The green stripe represents those genders outside and in-between the binary.
