The new autism symbol embraced by much of the autistic community is the rainbow infinity sign. It represents neurodiversity, infinite potential, and the idea that autism is a natural variation of human experience rather than a deficit. You’ll also see a gold infinity symbol used in similar ways. Both have gained momentum as alternatives to the traditional puzzle piece, which many autistic people consider outdated and offensive.
What the Rainbow Infinity Symbol Means
The rainbow infinity sign combines two ideas. The infinity loop represents the endless range of experiences and abilities across the autism spectrum. The rainbow colors reflect the diversity within the autistic community, with each color standing for different strengths, perspectives, and identities. The symbol is closely tied to the neurodiversity movement, which frames autism not as a disorder to be cured but as one of many natural ways the human brain can work.
Autistic Pride Day, celebrated annually on June 18, uses the rainbow infinity as its central image. For many autistic people, wearing or displaying the symbol is an act of identity and solidarity. As the organization behind Autistic Pride Day puts it, the symbol “represents a shift in the way we think about Autism, moving away from a focus on deficits and challenges and towards a more positive and accepting view.”
Why Gold Is Also Used
You may see a gold infinity symbol or simply the color gold used alongside or instead of the rainbow version. The connection comes from the periodic table: gold’s chemical symbol is Au, which also serves as shorthand for “autism.” Gold has become a color of autistic pride, often paired with the infinity shape. AutismBC, a Canadian advocacy organization, recognizes both red and gold as “affirming alternatives” to the older blue branding that dominated autism campaigns for years.
Why the Puzzle Piece Fell Out of Favor
The puzzle piece was introduced decades ago by parent-led organizations. It was meant to convey that autism was a “puzzling condition,” and its creators were explicit about this framing. One early supporter of the symbol explained that it “tells us something about autism: our children are handicapped by a puzzling condition; this isolates them from normal human contact and therefore they do not fit in.”
That message is exactly what autistic self-advocates object to. Critics argue the puzzle piece portrays autistic people as mysterious, incomplete, or missing something. Some imagery has gone further, depicting children with a literal puzzle piece cut out of their brain, or drawing children’s bodies in the shape of puzzle pieces. Research published in a peer-reviewed study found that these images shape how non-autistic children think about their autistic peers. When asked why some children have developmental disabilities like autism, kids aged 9 to 12 reported that “there is a puzzle piece missing in their brain.”
The backlash has been substantial. Autistic writers, academics, and advocates have published extensive critiques in journals, letters to editors, and online platforms. The objections aren’t fringe. Even the academic journal Autism was called out for using puzzle piece imagery on its cover and masthead.
The #RedInstead Movement
The shift away from the puzzle piece also involves color. For years, “Light It Up Blue” was the dominant autism awareness campaign, promoted by Autism Speaks. Many autistic people felt that blue was linked to narratives framing autism as something to be fixed. In response, the #RedInstead campaign emerged, encouraging people to wear red during April (Autism Acceptance Month) instead of blue. The Autistic Women & Nonbinary Network is credited with amplifying this movement, pushing the message that acceptance matters more than awareness.
Red and gold now serve as the primary colors of autistic pride and acceptance for many in the community, deliberately contrasting with the blue puzzle piece.
Where Major Organizations Stand
Autism Speaks, the largest and most visible autism organization, hasn’t abandoned the puzzle piece entirely but has softened it. In 2020, the organization unveiled a redesigned logo that evolved its iconic blue puzzle piece to include a spectrum of colors. The change was described as signaling “the diversity of perspectives and experiences with autism spectrum disorder” and a “deepened commitment to inclusivity.” The organization also switched to lowercase lettering in its name, part of a broader visual rebrand.
Still, many autistic-led organizations and advocates view any version of the puzzle piece as tied to a medical-deficit model of autism. The rainbow and gold infinity symbols remain the preferred choices among self-advocates, and their visibility continues to grow on social media, merchandise, and at pride events. If you’re looking for a symbol that aligns with how most autistic adults describe their own community, the infinity sign in rainbow or gold is the one you’ll see used most often.
