Just when you thought we’d seen it all—scientists have introduced a brand-new color to the human eye. Its name? Olo. And no, it’s not a weird shade of blue or a fancy remix of purple. It’s a completely new visual experience—something our eyes and brains aren’t naturally wired to see.

Developed by researchers at Dartmouth College, Olo is part of a category called "forbidden colors"—combinations of light that cancel each other out in normal vision. But in carefully controlled experiments, scientists found a way to override the brain’s usual filters, allowing test subjects to actually see this elusive hue.

So what does Olo look like? That’s the fun part: no one can really describe it. It’s been compared to glowing neon that doesn’t glow, or seeing green and red at the exact same time without them blending. It’s more of a sensation than a shade—a flash of color your mind can’t fully process, but knows is real.

In a world that often feels familiar and overstimulated, the discovery of Olo reminds us that wonder is still alive. There are still colors we’ve never seen.
