Flag and Symbols
The non-binary boy flag was designed by DeviantArt user Pride-Flags on January 17, 2017. Blue represents "boy" and yellow represents non-binary. Green represents a mix of boy and non-binary.
An alternate flag was designed by Brokenwings11ofnone on February 5, 2017. The color meanings are unknown, but are likely similar to the previous flag, though they are laid out similarly to the non-binary flag.
The second alternate non-binary man flag was designed by DeviantArt user Pride-Flags on July 4, 2015.
The non-binary man symbol was created by Tumblr user nbandproud on August 9, 2018. It is the male (Mars) symbol with an asterisk in the circle, coming from the non-binary symbol.
