Go Orange for Prader-Willi Syndrome: From Awareness Campaign to Global Movement
Each year throughout May, communities across Australia and around the world are encouraged to Go Orange for Prader-Willi Syndrome (PWS) a campaign that has grown from a grassroots Victorian initiative into a globally recognised movement for awareness and understanding.
At its simplest, the campaign asks people to wear orange and start conversations.
But Go Orange is more than a symbolic gesture.
It exists to address a critical gap, the lack of understanding surrounding Prader-Willi Syndrome and its real-world impact on individuals and families.

A Victorian initiative with global reach
Go Orange was established in 2013 by the Prader-Willi Syndrome Association of Victoria (PWSA Vic), driven by a small group of dedicated families seeking to bring visibility to a condition that was largely unknown.
At the time, awareness of Prader-Willi Syndrome was limited. Even where awareness existed, it was often accompanied by misunderstanding, particularly in relation to hyperphagia, behaviour, and emotional regulation.
Families were not only navigating the complexities of the condition itself, but also the consequences of misunderstanding across schools, healthcare settings, and the broader community.
Go Orange was created in response to this.
The idea was simple:
- Choose a colour
- Create visibility
- Start conversations
Orange became the recognised colour of PWS awareness, providing a consistent and accessible way for communities to engage.
Why orange? More than a colour
The choice of orange was not arbitrary.
Orange has historically been linked to hunger awareness, making it particularly relevant to PWS, where chronic hyperphagia (a neurological drive to eat) is one of the most defining and life-threatening features of the condition.
This is critical to understand:
Hyperphagia in PWS is not behavioural.
It is biological, neurological, and lifelong.
Research has consistently shown that individuals with PWS experience:
- Impaired satiety signalling
- Hormonal differences affecting hunger regulation
- Altered brain responses to food stimuli
This means that food-related behaviours are not a matter of choice or discipline, they are driven by the brain’s inability to regulate hunger appropriately.
By adopting orange, the campaign does more than create visibility.
It creates an entry point to educate the public about the reality behind the behaviour.

From local campaign to global movement
Like many awareness initiatives, Go Orange began with a focus on visibility, eSince its inception, Go Orange has grown significantly.
By 2017, the campaign had gained international recognition, with communities and organisations around the world participating in awareness activities and sharing campaign messaging.
Landmarks across the globe now light up in orange, communities host events, and individuals share stories to raise awareness of Prader-Willi Syndrome.
The strength of Go Orange lies in its accessibility anyone, anywhere can take part.
However, as the campaign has grown, so too has the recognition that visibility alone is not enough.
The evolution of Go Orange: From visibility to understanding
Like many awareness initiatives, Go Orange initially focused on visibility—encouraging people to wear orange and start conversations.
Visibility remains important.
But on its own, it is not enough.
Awareness without clear and accurate messaging can unintentionally reinforce misconceptions rather than challenge them, particularly for a condition as complex and misunderstood as PWS.
As the campaign has evolved, so too has its purpose.
Then: Wear orange to raise awareness
Now: Use visibility to drive understanding, inclusion, and meaningful change
This reflects a broader shift across disability advocacy—recognising that awareness is only the starting point.
Understanding is what leads to:
- More appropriate support
- Safer environments
- Reduced stigma
- Improved outcomes
Awareness starts the conversation.
Understanding changes the response.
The purpose of Go Orange today
For Go Orange to remain effective and credible, its purpose must be clearly defined.
It is not a generic awareness campaign.
It is a targeted initiative with clear objectives focused on improving understanding, reducing stigma, and supporting more informed, inclusive responses to Prader-Willi Syndrome.
As an awareness campaign, Go Orange does not replace clinical or specialist guidance.
Its role is to bridge the gap between lived experience and everyday understanding, supporting not only professionals, but also families, friends, extended support networks, and the broader community to better understand and respond to Prader-Willi Syndrome.
The campaign aims to:
Improve understanding
Supporting those who want or need to better understand Prader-Willi Syndrome, including families, friends, extended family members, educators, and the general public, particularly in relation to the neurological and physiological drivers behind behaviour.
Reduce stigma
Challenging misconceptions and encouraging more informed, compassionate responses across the community.
Promote safer, more inclusive environments
Increasing awareness to help with structures and supports required for individuals with PWS to be safe and meaningfully included across home, school, and community settings.
Support community response
Equipping families, peers, educators, and the broader community with the awareness needed to respond in ways that are respectful, appropriate, and informed.
Continue evolving through lived experience
Modern awareness campaigns are most effective when informed by lived experience. This is an area Go Orange continues to grow into, strengthening the visibility of real stories by sharing family voices, and the day-to-day realities of living with PWS.
Unify a global community
What began in Victoria now connects families, extended support networks, organisations, researchers, and advocates internationally, strengthening messaging, advocacy, and community connection.
The real-world impact of understanding
The difference between awareness and understanding has tangible, real-world consequences for individuals living with Prader-Willi Syndrome and their families.
When communities understand PWS:
- Children are better supported within school environments
- Families experience reduced judgement and social isolation
- Environments are structured to promote safety and consistency
- Individuals are given greater opportunity to participate, engage, and thrive
When understanding is lacking:
- Risk increases, particularly in relation to food security and supervision
- Inappropriate responses and mismanagement occur
- Stigma and misconceptions persist
- Outcomes for individuals and families are significantly compromised
This is not theoretical.
It is the lived reality for families navigating Prader-Willi Syndrome every day.
More than awareness
Go Orange is more than a campaign.
It is a response to misunderstanding.
It is a driver of inclusion.
Most importantly, it is a reminder that:
When people understand Prader-Willi Syndrome, they respond differently.
And that difference has the power to change lives.
🧡 Colour the World Orange – May 15
Each year in MAY, we call on our community, and the broader public, to Colour the World Orange in recognition of Prader-Willi Syndrome.
This is more than a symbolic gesture.
It is a coordinated, visible act of awareness designed to spark conversation, challenge misconceptions, and bring Prader-Willi Syndrome into the public eye.
On this day, we invite individuals, families, schools, workplaces, and communities to take part in a simple but powerful way – by going orange.
- Wear your orange t-shirt.
- Paint your nails.
- Add a splash of orange to your outfit, your workplace, or your school environment.
- Host an “Orange Day” with balloons, streamers, and activities that encourage conversation and learning.
- Start discussions with peers, colleagues, and students about what Prader-Willi Syndrome is, and what it isn’t.
The action itself is simple – The impact is not.
Every orange item worn, every conversation started, and every space transformed creates an opportunity to increase understanding and visibility for a condition that is too often misunderstood.
Because when the world stops to ask, “Why orange?”— we create the moment to answer.
And that is where awareness becomes understanding.
