The non-binary pride flag was made by a teenager for people the existing flags kept missing. Four equal stripes, yellow, white, purple, and black, posted to Tumblr in February 2014 by 17-year-old Kye Rowan, and now flown from government buildings and Eurovision stages. Its premise is coverage: between a color for genders outside the binary, a color for many genders, a color for mixed genders, and a color for no gender at all, every non-binary person is supposed to find their stripe.
A gap in the flags
By 2014 the vocabulary of gender identity was expanding faster than its symbols. The transgender flag, Monica Helms's pink, blue, and white design from 1999, covered the broad trans umbrella but was strongly associated with binary trans men and women. The genderqueer flag existed too: Marilyn Roxie had designed it in 2011, with a lavender stripe for androgyny, white for agender identities, and dark chartreuse green for third-gender and other identities defined outside the binary.
But "genderqueer" and "non-binary" were not quite the same word, and a growing number of people who used the second did not feel described by the first. Rowan, then 17, created the four-stripe flag in February 2014 in response to calls from exactly that group: non-binary people who felt the genderqueer flag did not represent them. Rowan was explicit that the new flag was meant to fly beside Roxie's, an addition to the family rather than a coup.
The timing was good. Over the following five years "non-binary" became the dominant umbrella term in English, adopted in surveys, style guides, and legislation, and the flag rode the word. By the time major institutions needed something to raise for non-binary constituents, Rowan's design was the obvious candidate.
Four stripes, read literally
The flag's color logic is unusually systematic. Yellow, the first stripe, is for people whose gender exists outside the binary entirely, and the choice is pointed: yellow is a primary color, not a mixture, and it has no relationship to the pink and blue that gender the rest of the culture. White, which combines all colors of light, is for people who have many genders or all of them. Purple, the blend of pink-adjacent red and blue, is for people whose gender is a mix of male and female or sits somewhere between them; it also nods to the long association of lavender and purple with queer communities. Black, the absence of color, is for agender people, those with no gender at all.
The commonly cited values are #FFF433 for the yellow, white, #9B59D0 for the purple, and #2D2D2D for the black, a dark charcoal rather than pure black. There is no official standard, and manufacturers drift, but the four-stripe structure never varies. The design's plainness is deliberate. Like Helms's transgender flag, it uses simple horizontal bands that a child could draw, and its palette survives being shrunk to a pin badge or a 16-pixel icon, which is where most flags now live most of the time.
Alongside, not instead
The non-binary flag's relationship to its neighbors is cooperative by design. Rowan never positioned it against the genderqueer flag, and both remain in use, sometimes side by side at the same event, with Roxie's design now read as the more specific and historical of the two. The transgender flag covers many of the same people, since many but not all non-binary people also identify as trans, and the two flags are often flown together. The Progress Pride flag places non-binary people inside its chevron via the trans colors rather than Rowan's palette.
That stack of overlapping symbols draws the same criticism every new pride flag draws: that the proliferation fragments a movement which once had a single rainbow. The counterargument is practical. A non-binary teenager scanning a crowd is not looking for a symbol of the whole movement; they are looking for proof that people like them, specifically, are present. The yellow-white-purple-black flag is legible to exactly that reader and nearly invisible to everyone else, which is roughly the job description.
Eurovision and after
The flag's most public moment came in May 2024 at the Eurovision Song Contest in Malmö. Eurovision's flag policy that year admitted only competing countries' national flags and the rainbow flag, which excluded the non-binary flag. Nemo, the Swiss entrant and a non-binary artist, carried one in anyway and displayed it during the opening ceremony, then won the contest with "The Code," a song about coming to terms with a non-binary identity. "I had to sneak in the flag of my non-binary gender because Eurovision told me I couldn't take it out," Nemo said afterwards. "I did it anyway." The European Broadcasting Union said the policy would be reviewed, and the exchange put the flag on front pages across Europe.
Away from the spotlight, the flag has settled into the institutional calendar. It flies on International Non-Binary People's Day, July 14, a date picked for its position halfway between International Women's Day and International Men's Day, and during Non-Binary Awareness Week around it. It has no emoji: Unicode's flag policy effectively limits new flag emoji, so the transgender flag, admitted in 2020, remains the closest available stand-in. Rowan's original Tumblr post, meanwhile, has the distinction shared by Helms's and Page's designs before it: a flag made by one person, for free, that institutions now raise on poles.
