Hanky code is the best-known signalling system in gay male fetish culture, and also the most misunderstood. A coloured handkerchief in a back pocket was supposed to announce what someone was into, left for the active role, right for the passive one. Sixty years later the colours have spread onto armbands, vest piping and, inevitably, pup hoods. That last step is where the confusion starts, because a hood is not a handkerchief and its colour was never part of any code.
Nobody knows who invented the hanky code
The honest answer is that the origin is undocumented, and the people who have spent years in the archives say so plainly.
Three stories, none of them confirmed
Gary Wasdin, executive director of the Leather Archives and Museum in Chicago, points out the obvious problem: nobody was writing this down. “It’s always difficult to figure out where and when it actually started,” he told Metro Weekly in January 2026. What he can say is where it took hold. The practice spread in the early 1970s in San Francisco and New York, cities with large queer populations on foot, because signalling only works if people can see you. A hanky read through a car window is useless.
Adam Campbell, associate professor at the University of Southern California and author of Bound Together: Leather, Sex, Archives, and Contemporary Art, found evidence pointing somewhere less romantic: early motorcycle clubs, where men carried handkerchiefs to maintain their bikes and to complete a look. He also found a letter to the editor in a 1976 issue of Drummer claiming the whole thing was a press hoax seeded by a Village Voice article on S&M. “I was never able to confirm that claim,” he says. Vice went looking for the inventor in 2011 and concluded the person would remain unremembered.
What the printed record actually shows
The paper trail is thin and late. Drummer published its code in 1977. Bob Damron’s Address Book began carrying yearly updates in 1980. The version most often treated as authoritative, Larry Townsend’s The Leatherman’s Handbook II, appeared in 1983, and the colour list is absent from the first edition. In other words, the hanky code circulated by word of mouth for a decade before anyone printed a reference, which is exactly why no single version is the real one.
How the code worked when people actually used it
Left pocket, right pocket
The one rule everybody still remembers is the placement. Worn on the left, the colour claimed the active role; worn on the right, the passive one. That half of the hanky code was borrowed from an older habit, hanging your keys on one side or the other, and it is the only part of the system that stayed stable across every published list. The colours were negotiable. The sides were not.
A dozen printed colours, six or eight in real use
Frank Nowicki, a Centaur Motorcycle Club member and 1993 Mr. Mid-Atlantic Leather, was there. He remembers the practice as routine in 1970s bars, and he also remembers its limits: the earliest published lists ran to about a dozen colours, but only six or eight were used in practice. Everything beyond that was decoration.
That gap has only widened. Wasdin describes today’s list as so extravagantly long that memorising it is impossible, so people simply learn the colours they care about. A system nobody can read in full is not a language. It is a vocabulary people dip into.
The ambiguity was there from the first documentation
Gay Semiotics, San Francisco, 1977
In 1977, the photographer Hal Fischer published Gay Semiotics, a study of visual coding among gay men in the Castro and Haight-Ashbury. The series, now in the collection of the Museum of Modern Art, includes images titled Blue Handkerchief, Red Handkerchief and Keys, each annotated with the meanings those objects were meant to carry.
What makes the work useful is the caveat Fischer wrote into it. Alongside the meanings, the text notes that the man might simply be carrying a handkerchief to blow his nose. The very first serious documentation of the hanky code already said the sign could not be trusted on its own.
Why a pup hood is not hanky code
Pup gear grew out of the same leather world, so the assumption spread that hood colours were coded too. Some retailers leaned into it and sold pup-specific handkerchiefs, aligning their ranges with the hanky code as closely as they could. Others simply sold every colour they could produce.
What the research actually says about pup gear
The largest published survey of pup play, run by Liam Wignall and colleagues and published in Archives of Sexual Behavior in 2022, covers 733 participants. Gear is close to universal: 90.9% own some, and hoods or masks are the single most common piece at 81.86%, ahead of collars at 78.44% and harnesses at 63.17%. Asked how important gear is to expressing a pup identity, participants averaged 4 out of 5, with 53.61% calling it important or extremely important.
Here is the telling part. The researchers did ask whether the colour of the gear mattered to participants, and the published paper does not report the answer. The one large study on the table put the question and left it out. The survey is also self-selected and mostly American, which its authors acknowledge.
The 25% figure has no source
The number that circulates in pup circles is that only 25% of pups pick a hood colour according to the hanky code. It comes from a single blog post by PupUmbreon on pupplay.info, dated 24 July 2017, and no survey, sample or method is cited anywhere in it. Other sites now quote 32% and 60% with equally little behind them. Treat all three as folklore.
What a hood colour does say
Identity, not instruction
Wignall’s team make a point that fits what anyone at a mosh can see: customisable hoods let people match their gear to their pup identity and be recognisable in a crowd. Colour here is closer to a football strip than a fetish menu. It marks a pup persona, a pack, a favourite colour, or nothing at all beyond what looked good online at two in the morning. None of that is hanky code, and none of it is meant to be read as one. The puppy play flag works the same way: its colours carry meaning for the community, not instructions about a wearer’s sex life.
Even among veterans, the older system has drifted the same direction. As Wasdin puts it, wearing a yellow hanky today signals something he is into in general, not a proposition on the spot. The hanky code has become less about cruising and more about identity.
Reading colour today without getting it wrong
Ask, don’t assume
The practical rule is unchanged since Fischer photographed it in 1977: a colour is an opening, not an answer. Someone flagging a colour deliberately still has to be asked what they mean by it, and someone wearing a red hood has most likely never thought about the hanky code at all. Assuming otherwise is how a new pup ends up propositioned for something they have never done.
Consent runs on words. Colour can start the conversation, a safeword governs what happens after it, and nothing worn on a body replaces either. That was true when the code was a dozen colours in a leather bar, and it is truer now that the list has no end.
