Intersex Pride Flag Meaning, Designer & Variation
The short version
- Intersex describes people born with sex characteristics (chromosomes, hormones, anatomy) that don't fit typical definitions of male or female. "Intersex variation" is the modern, neutral term; older medical labels like "hermaphrodite" are outdated and offensive.
- Intersex is about biology. Transgender is about gender identity. They're separate; intersex people can be cis or trans, of any gender or orientation.
- The intersex pride flag was designed by Morgan Carpenter in July 2013 for Organisation Intersex International Australia. It's a yellow background with a purple circle in the centre.
- Yellow and purple were chosen specifically because they're outside typical gendered colour palettes. The unbroken circle represents wholeness, completeness, and the right to bodily autonomy.
- Estimates put intersex variation at roughly 1.7% of people (some sources cite a 1-2% range), about as common as having red hair. It's not rare; it's just rarely talked about openly.
We're Delwin and Jimmy, co-founders of Proud Zebra, a queer-owned Canadian small business designing pride pins and accessories from the Lower Mainland, BC. Intersex is one of the most-misunderstood identities in our pride festival booth conversations. Most of those conversations start with someone confusing intersex with trans, or assuming intersex people are extremely rare. Both of those assumptions are wrong, and this guide is here to lay out the actual picture.
This guide covers what intersex means, what the flag represents, who designed it, and the critical distinction between intersex and trans identity. It's part of our complete guide to LGBTQ+ pride flags.
What does intersex mean?
Intersex describes people born with sex characteristics (chromosomes, hormones, gonads, or anatomy) that don't fit typical definitions of male or female. The variation can be visible at birth, emerge at puberty, or only become apparent later through fertility testing, surgery, or genetic screening. Some intersex people know their status from birth; others discover it as adults.
Intersex is not a single condition; it covers many specific variations. Some examples:
- Variations in chromosomes beyond XX or XY (such as XXY, XYY, or X)
- Variations in hormone production or response (including conditions like complete androgen insensitivity)
- Anatomical variations that don't fit typical male or female categories
- Variations in internal reproductive structures
According to interACT, the leading US intersex youth advocacy organization, roughly 1.7% of people are born with an intersex variation (some sources cite a broader 1-2% range, depending on which variations are counted). That's about as common as having red hair. Intersex is not rare; it's been kept invisible by medical and social norms that treated intersex variations as conditions to be hidden, surgically altered, or assigned away.
Is intersex the same as transgender?
No. Intersex is about biology; transgender is about gender identity. The two get conflated regularly, and it's worth being precise:
| Aspect | Intersex | Transgender |
|---|---|---|
| What it describes | Biological sex characteristics that don't fit typical male/female categories | Gender identity that differs from the gender assigned at birth |
| When it's determined | At birth or later (biological reality) | Self-identified (felt sense of who you are) |
| About the body or the self? | The body's physical sex characteristics | The person's gender identity |
| Can someone be both? | Yes. Intersex and trans are independent. An intersex person can be cisgender or transgender. | |
An intersex person assigned female at birth who identifies as a woman is intersex and cisgender. An intersex person assigned female at birth who identifies as a man is intersex and transgender. The two categories describe different things and overlap or stay separate depending on the individual.
The conflation comes partly from both communities being part of broader LGBTQ+ conversations and partly from outdated medical framing. Intersex advocacy organizations have spent decades pushing for the distinction to be made clearly.
What does the intersex pride flag look like?
The intersex pride flag is a yellow background with a purple circle in the centre. The circle is unbroken and unornamented.
The colour and symbol choices were deliberate:
- Yellow background, chosen specifically because it's outside the typical pink-and-blue gendered colour palette.
- Purple circle, also outside gendered colour conventions; together with yellow, the palette signals an identity that exists outside binary frameworks.
- The circle is unbroken, representing wholeness, completeness, and bodily integrity.
- The circle is unornamented, no internal markings, symbols, or division. Intersex bodies are whole as they are.
Who designed the intersex pride flag?
Morgan Carpenter designed the intersex pride flag in July 2013 for Organisation Intersex International Australia (OII Australia, now known as Intersex Human Rights Australia). Carpenter is an Australian intersex activist, researcher, and human rights advocate.
In the original announcement, Carpenter wrote:
"We have chosen yellow and purple, considered hermaphrodite [colours], specifically not gendered. The circle is unbroken and unornamented, symbolising wholeness and completeness, and our potentialities. We are still fighting for bodily autonomy and genital integrity, and this symbolises the right to be who and how we want to be."
Morgan Carpenter, OII Australia, July 2013
The reference to bodily autonomy and genital integrity is intentional and central. Many intersex children are subjected to non-consensual surgeries to "normalize" their bodies into typical male or female categories. These surgeries often happen in infancy, before the child can consent, and have lasting physical and psychological consequences. Stopping these non-consensual surgeries is one of the central goals of modern intersex advocacy.
Intersex vs the older "hermaphrodite" term, what's the difference?
"Intersex" is the modern, community-chosen term; "hermaphrodite" is an outdated medical label that intersex people have explicitly rejected. If you've landed here searching "intersex vs hermaphrodite," the short answer is: use "intersex." The older word originated in 19th-century medicine, carries a long history of stigma and non-consensual surgery, and intersex advocacy organizations (including interACT and Intersex Human Rights Australia) have spent decades pushing for it to be retired in human contexts. It's still used biologically when describing certain non-human species; it's not appropriate for people.
The shift mirrors what happened with other identity terminology: the community most affected chose its own language, and the older label became a marker of either outdated training or active disrespect. If you're talking about, writing about, or supporting an intersex person, the term is intersex.
How is intersex represented in modern pride symbols?
The standalone intersex flag remains the primary visual symbol, but intersex inclusion has also been built into broader pride imagery in recent years. The most visible example: in 2021, intersex activist Valentino Vecchietti updated the Progress Pride Flag to include the intersex symbol, adding a yellow triangle with a purple circle on the white tip of Daniel Quasar's chevron. The result is the Intersex-Inclusive Progress Pride Flag, now the most widely-flown version of the design.
The "I" in the longer LGBTQI+ acronym (or 2SLGBTQI+ in many Canadian usages) explicitly stands for intersex. Adding the I was a deliberate visibility move to ensure intersex inclusion isn't optional. For the broader gender-spectrum context that intersex sits adjacent to, see our non-binary and genderqueer guide.
Despite this, intersex visibility lags behind other LGBTQI+ identities in mainstream pride imagery. Many "rainbow flag" pride contexts default to symbols that don't include intersex representation. The dedicated yellow-and-purple flag exists precisely so intersex people can claim visibility on their own terms.

Frequently asked questions
What does intersex mean?
Intersex describes people born with sex characteristics (chromosomes, hormones, gonads, or anatomy) that don't fit typical definitions of male or female. The variation can be visible at birth, emerge at puberty, or be discovered later. It's a broad category covering many specific biological variations, not a single condition. Roughly 1.7% of people are born intersex.
Is intersex the same as transgender?
No. Intersex is about biology (sex characteristics that don't fit typical male or female categories). Transgender is about gender identity (having a gender identity that differs from the one assigned at birth). The two are independent. An intersex person can be cisgender or transgender; their intersex status doesn't determine their gender identity.
Who designed the intersex pride flag?
Morgan Carpenter, an Australian intersex activist and researcher, designed the intersex pride flag in July 2013 for Organisation Intersex International Australia (now Intersex Human Rights Australia). The yellow background and purple circle were chosen specifically because they're outside typical gendered colour palettes.
What does the intersex flag symbolize?
The yellow and purple colours sit outside typical pink-and-blue gendered colour conventions. The unbroken purple circle represents wholeness, completeness, and bodily integrity. The unornamented design (no internal markings) signals that intersex bodies are whole as they are. The flag carries an explicit advocacy message: the right to bodily autonomy, particularly the right of intersex children not to be subjected to non-consensual surgeries.
Should "hermaphrodite" be used to describe intersex people?
No. "Hermaphrodite" is an outdated and offensive term for intersex people. It's a medical-historical term that intersex communities have explicitly rejected. The correct term is "intersex," which intersex people chose for themselves. The only appropriate use of "hermaphrodite" is in historical or biological contexts referring to non-human species, never to describe intersex people.
Carrying the flag forward
Intersex visibility is still catching up to where it should be. The flag, the LGBTQI+ acronym's I, the Intersex-Inclusive Progress Pride Flag, Intersex Awareness Day, all are part of the same long-running push to make a community of roughly 1.7% of people no longer invisible.
If you wear the standalone intersex flag, an Intersex-Inclusive Progress Pride Flag pin, or one of the more specific identity flags from our complete pride flags guide, you're carrying forward visibility for an identity that mainstream pride imagery has historically left out.
