Sometimes life throws you a curveball in the most unexpected ways. For Japanese illustrator Mikan Noka, that moment came when he shared what he thought was a perfectly normal illustration of his favorite character—only to discover something life-changing about himself in the process.
On November 19th, Mikan Noka posted his latest artwork featuring Izumi Dougo, a character from the Onsen Musume franchise. To him, everything looked fine. The colors were balanced, the shading was on point, and he was proud of the result. But his followers immediately noticed something unusual: the character’s skin was completely green.
At first, the comments might have seemed like typical internet trolling. “Why is she green?” “Did you mean to do that?” But as more people pointed it out, Mikan Noka realized something wasn’t adding up. To his eyes, the illustration looked completely normal—the skin tone appeared natural and correct. That’s when it hit him: the problem wasn’t with the artwork, it was with his perception.
An unexpected diagnosis through art
What started as a simple post turned into a moment of self-discovery. Thanks to the feedback from his community, Mikan Noka learned that he has a form of color blindness affecting how he perceives certain hues. For years, he’d been creating art without realizing that the colors he saw weren’t quite what everyone else was seeing.
Color blindness, or color vision deficiency, affects millions of people worldwide, though many don’t realize they have it until a situation like this arises. For an artist, this discovery could have been devastating—imagine learning that your primary tool for expression has been showing you a different reality all along.

When the internet gets it right
Here’s where the story takes a heartwarming turn. Instead of mockery or ridicule, the internet did something surprisingly wholesome. The illustration went viral, but not as a joke at the artist’s expense. The community rallied around Mikan Noka, turning what could have been an embarrassing moment into a celebration.
“Green Izumi” became an instant phenomenon. Fans embraced the accidental color palette, creating fan art, memes, and tributes to the emerald-skinned version of the character. What was initially a mistake transformed into something uniquely special—a character variant born from an honest human experience.
Mikan Noka has been actively engaging with fans since the discovery, showing remarkable grace and humor about the situation. Rather than letting this revelation discourage him, he’s used it as an opportunity to connect with his audience on a deeper level and learn more about his condition.
A new perspective
This story resonates beyond just the anime and illustration community. It’s a reminder that our perceptions of reality can differ in ways we never imagine, and that sometimes our “mistakes” can lead to unexpected discoveries—both about ourselves and the communities we’re part of.
For Mikan Noka, this experience has likely changed how he approaches his craft. Many digital art programs include colorblind-friendly tools and filters that can help artists verify their color choices. It’s a challenge, certainly, but one that countless artists have navigated successfully.
And honestly? Green Izumi kind of works. There’s something charming about a character design that exists purely because of a unique way of seeing the world.
