You’ve probably seen the photos. They look like a bad Photoshop job or maybe a leftover prop from a big-budget sci-fi movie. But the reality of the person with blue skin isn’t found in a Hollywood studio. It’s found in the rugged, isolated hills of Troublesome Creek, Kentucky.
Blue skin is real.
It isn't a myth. It isn't a hoax. It’s a rare medical phenomenon that turned a regular family into a national curiosity for over a century. Honestly, when people first hear about the "Blue Fugates," they assume it’s an urban legend, like Bigfoot or the Mothman. But the science behind it is actually pretty straightforward, even if the results look like something out of a fantasy novel.
The Family That Turned Blue
The story starts in 1820. Martin Fugate, a French orphan, settled in eastern Kentucky. He was, by all accounts, a normal-looking guy, except for one tiny, invisible detail hidden in his genetic code. He met and married Elizabeth Smith. She was pale and red-headed. By a statistical miracle—one that defies most odds—Elizabeth carried the exact same rare, recessive gene that Martin did.
They had seven children. Four of them were born with blue skin.
Imagine living in a remote Appalachian holler in the 19th century and having a child who is literally the color of a bruised plum. There were no doctors nearby to explain it. No Google to search for answers. The community reacted with a mix of awe and fear. Because the area was so isolated, the family naturally began to intermarry with nearby clans like the Combs, Richies, and Stacys. This kept the "blue gene" trapped in a small geographic loop for generations.
It wasn't just a slight tint. We’re talking about a deep, indigo hue. People who saw them described their skin as being the color of a lake on a cool day.

Why Does Someone Turn Blue?
Let's get into the weeds of the science because it's fascinating. The condition is called methemoglobinemia.
Usually, our blood is bright red because the hemoglobin carries oxygen throughout the body. In a person with blue skin, the hemoglobin is replaced by methemoglobin. This version of the protein is a bit of a hoarder; it carries oxygen but won't release it into the tissues. When your tissues are deprived of that oxygen-rich red blood, they turn blue. It’s essentially a permanent state of cyanosis, the same thing that happens to your fingernails or lips when you’re freezing cold.
In the case of the Fugates, it was a hereditary deficiency of an enzyme called diaphorase. Without this enzyme, the body can't convert methemoglobin back into regular, functional hemoglobin.
The Madison Cawein Breakthrough
By the 1960s, a hematologist named Dr. Madison Cawein heard rumors about these blue people. He went hunting for them in the Kentucky hills. He eventually found Patrick and Rachel Ritchie, who were reportedly quite embarrassed by their appearance.
Cawein was a smart guy. He knew about similar cases among Alaskan Eskimos and realized it was likely an enzyme issue. He didn't use some high-tech, futuristic cure. He used something incredibly counterintuitive: methylene blue.
It sounds like a joke. You give a blue person a blue dye to turn them pink? But it worked. Methylene blue acts as an electron donor that helps the body process the methemoglobin. Within minutes of being injected, the blue tint faded. For the first time in their lives, the Ritchies saw pink in their own skin.

They had to take the dye in tablet form every day to keep the color away. If they missed a dose, the blue would slowly creep back into their fingers and faces.
It’s Not Just Genetics
While the Fugates are the most famous example, you can actually "make" yourself a person with blue skin through external factors. This is a crucial distinction. The Fugates were healthy; they lived into their 80s and 90s despite their odd color. But acquired methemoglobinemia can be dangerous.
Exposure to certain chemicals can trigger it:
- Certain topical anesthetics (like benzocaine)
- Nitrates in well water
- Specific antibiotics or heart medications
There is also the case of Argyria. This is totally different from the Fugate condition. Argyria happens when someone consumes too much silver. The most famous modern "Blue Man" was Paul Karason. He had a skin condition and decided to treat it by drinking colloidal silver and rubbing it on his face.
The silver built up in his tissues. When sunlight hit his skin, it reacted just like silver does in old-school photography—it turned dark and bluish-grey. Unlike the Fugates, Karason’s condition was permanent. No amount of methylene blue could fix it because the metal was literally embedded in his cells. He passed away in 2013, but he remains a cautionary tale about DIY medical treatments.
Living as a Blue Person
The social impact of being a person with blue skin in a small town can't be overstated. The Fugates were incredibly private. They were often the target of local gossip, and many viewed their skin color as a mark of shame or a sign of "bad blood."

They weren't "sick" in the traditional sense. They didn't have trouble breathing, and they weren't weak. They were just... blue.
As the 20th century progressed, the isolation of Appalachia broke down. People moved away. New families moved in. The gene pool widened. The recessive gene started to hide again, only popping up when two carriers happened to meet.
The last known descendant born with the blue trait was Benjamin Stacy in 1975. When he was born, he was so dark blue that doctors were terrified he was dying. They were about to give him a blood transfusion when his grandmother mentioned the "Blue Fugates." Once they realized it was just the family trait, the panic subsided. Benjamin eventually "grew out" of his blue color as he got older, though his lips and fingernails would still turn blue when he got angry or cold.
Misconceptions That Stick Around
People love to sensationalize this. You'll see articles claiming the Fugates were an alien race or that they were a separate species of human. That’s nonsense. They were humans with a very specific, very rare metabolic quirk.
Another myth is that they were "inbred" to the point of deformity. While the isolation of the area did lead to intermarriage—which is how recessive genes find each other—the family wasn't "deformed." Aside from the color, they were physiologically normal. In fact, many lived exceptionally long lives for that era.
What to Do If You See Blue
If you ever encounter someone who appears to be a person with blue skin, or if you notice your own skin taking on a blue or purple tint, the first step is always medical intervention.
- Check for Oxygen: In most modern cases, blue skin (cyanosis) is an emergency. It usually means your lungs or heart aren't getting enough oxygen to your blood. This is not the "Fugate blue"; this is a "call 911" blue.
- Review Medications: If you've been using a lot of numbing creams or taking new medications, mention this to a doctor. Methemoglobinemia can be induced by common drugs.
- Well Water Testing: If you live in a rural area and have infants, get your well water tested for nitrates. High nitrate levels can cause "Blue Baby Syndrome," which is a form of methemoglobinemia that can be fatal for newborns.
- Avoid Colloidal Silver: Despite what some corners of the internet say, drinking silver is not a cure-all. It has no proven health benefits and carries the very real risk of turning you permanently grey-blue.
The legacy of the blue people of Kentucky serves as a wild reminder of how much we still don't know about our own biology. It's a story of isolation, a freak accident of genetics, and a doctor who found a cure in an ink-colored bottle. Today, the blue gene likely still exists in the descendants of the Fugates, scattered across the country, hidden behind more common skin tones, waiting for the right match to show its face again.
