The flag was designed by Rainbowraven96 on February 13, 2021. The yellow-orange gradients at the top and the bottom of the flag represent all times of day when the sun is up, and they encompass the spectrum between pink (female or fiaspec), blue (masculine and miaspec) and yellow (neutral and niaspec) genders, representing feeling miaspec, fiaspec, and niaspec when the sun is up.
