You've probably seen them. Those grainy, slightly unsettling photos of blue people that pop up on Reddit or in old medical textbooks. Usually, someone is claiming they're "aliens" or a "government hoax." But the truth is actually way more interesting than a sci-fi flick. It’s a mix of genetic bad luck and some very strange chemistry.
Seriously. People have actually turned blue.
When we talk about photos of blue people, we aren't talking about Smurfs or CGI. We’re talking about real human beings who, due to specific medical conditions, developed a skin tone ranging from a light lavender to a deep, bruised indigo. It’s a phenomenon that hits at the intersection of hematology, history, and pure chance.
The Blue Fugates: A Genetic Fluke in the Hills
The most famous instances of this aren't from a lab. They're from Troublesome Creek, Kentucky. In the early 1800s, an orphan named Martin Fugate settled there. He married Mary Smith. Neither of them knew they both carried a recessive gene for a rare condition called methemoglobinemia.
Genetics are weird.
Because they lived in such an isolated area, the family stayed small and local. Inbreeding occurred—that’s just the historical reality of 19th-century Appalachia. This meant the recessive gene didn't get "washed out" of the gene pool. Instead, it became a family trait. For over a century, the Fugates produced children who were literally blue.
If you look at the rare photos of blue people from this lineage, you’ll notice they look perfectly healthy otherwise. They weren't sick. They just couldn't carry oxygen in their blood the way you or I do.
Why the blood turned blue
Normally, hemoglobin carries oxygen through your veins. It’s what makes your blood look bright red when it hits the air. But with methemoglobinemia, the iron in the hemoglobin is "stuck" in a state where it can't bind to oxygen effectively.

It becomes methemoglobin.
When you have high levels of this, your blood turns a dark, chocolatey brown. Through the translucent layers of the skin, that brown-black blood makes the person look blue. Dr. Madison Cawein, a hematologist who eventually treated the family in the 1960s, described their skin as being the color of a "cool lake on a summer day."
Paul Karason and the Silver Trap
Not every blue person was born that way. Take Paul Karason. You might remember him as "Papa Smurf" from the news cycles in the late 2000s. Unlike the Fugates, Paul wasn't born blue. He made himself blue.
He had a bad case of dermatitis and started self-treating with colloidal silver.
He didn't just use a little. He drank it. He rubbed it on his face. He did this for years. The result was a condition called argyria. It’s basically permanent. Once silver particles lodge in your skin and organs, they don't leave. When sunlight hits those particles, they undergo a chemical reaction—sort of like how old-school photographic film develops. It turns the skin a permanent, slate-gray blue.
Argyria is a fascinating cautionary tale.
Unlike the Fugate family, whose blue tint could actually be cured with a simple dose of methylene blue (a blue dye that, ironically, turns the blood red again), argyria is forever. There is no pill to suck the silver out of your dermis.

Misconceptions in Modern Media
A lot of people confuse these real medical cases with "Colloidal Silver" marketing or even the "Blue Man Group." Let’s be clear: the Blue Man Group is wearing greasepaint. The photos of blue people you see online that look "too bright" are usually edited or theatrical.
Real pathological blueness is subtler.
It shows up most clearly in the lips and fingertips. In medical terms, this is often called cyanosis. If you see someone turn blue suddenly, it’s a medical emergency—it means they aren't breathing. But for the Fugates, it was just Tuesday.
The Methylene Blue Irony
One of the wildest parts of the Fugate story is the cure.
Dr. Cawein suspected the issue was a lack of an enzyme called diaphorase. To test it, he injected the family members with methylene blue dye.
You’d think adding blue dye to a blue person would make it worse, right? Nope. The dye acts as an electron donor, converting the "bad" methemoglobin back into "good" oxygen-carrying hemoglobin. Within minutes, the blue color faded. Their skin turned pink for the first time in their lives.
They had to take the dye in pill form regularly to keep the color away.

The Ethics of the "Blue" Label
It’s easy to look at these photos and see a curiosity. A freak show. But for the people living it, it was a source of massive social stigma. The Fugates were incredibly shy. They hid from outsiders because people in town associated the color with "bad blood" or "sin."
Even Paul Karason, who went on The Today Show, eventually grew tired of the "Papa Smurf" nickname.
We have to remember that behind every one of these photos of blue people is a person who had to navigate a world that isn't kind to those who look different. The Fugate line eventually "faded" out as the family moved away from Troublesome Creek and married people without the recessive gene. The last known "blue" descendant, Benjamin Stacy, was born in 1975. He was born dark blue, which terrified the doctors, but he eventually lost the tint as he grew older, only turning blue when he got really cold or angry.
What to Look For
If you’re researching this, stick to reputable medical archives.
- Look for University of Kentucky records regarding Dr. Madison Cawein.
- Check the National Center for Biotechnology Information (NCBI) for case studies on hereditary methemoglobinemia.
- Avoid "creepypasta" sites that use these photos to tell ghost stories.
Real Insights for Researchers
If you or someone you know is showing signs of blue skin (cyanosis), skip the internet rabbit hole and go to an ER. It usually means oxygen deprivation.
However, if you're just a history buff, the best way to understand this is to look at the pedigree charts of the Fugate family. It’s a masterclass in how isolation affects human biology.
Next Steps for Action:
- Verify the Source: If you see a "blue person" photo on social media, check if it’s attributed to the Fugate family or Paul Karason. If not, it’s likely a digital edit.
- Study Recessive Genetics: Use the Fugate case as a way to understand how CYB5R3 gene mutations work. It’s the primary cause of Type I methemoglobinemia.
- Check Your Supplements: If you use colloidal silver, talk to a dermatologist. Argyria is rare but irreversible, and the "blue" look starts in the gums before it hits the skin.
- Medical Literacy: Learn to distinguish between central cyanosis (whole body) and peripheral cyanosis (just hands/feet), as they indicate very different health issues.
