Scientists have claimed to have discovered a new color that no human has ever seen before.

According to reports from international news agencies, researchers state that by stimulating specific cells in the retina, they observed a blend of blue and green — a new color they’ve named “Ollo.” However, some experts suggest that the existence of this color may still be open for debate and further investigation.

A co-author of the study, published in a scientific journal and a professor at the University of California, described the breakthrough as “remarkable” and suggested that these findings could lead to deeper research on color blindness.

One of the five participants in the experiment, Professor N.G., said:

“Ollo is richer than any color you can see in the real world.”

🔬 The Experiment:

• The team conducted an experiment involving 5 participants (4 men and 1 woman).

• Researchers shone a laser beam into the pupil of one eye of each participant.

• Participants viewed the color using a device called OZ, composed of lenses, lasers, and optical components.

• Originally designed by scientists at UC Berkeley and the University of Washington, the device was upgraded for this study.

👁️ Understanding the Retina:

The retina is a light-sensitive tissue at the back of the eye that captures and processes visual information. It converts light into electrical signals, which are sent to the brain via the optic nerve, allowing us to see.

The retina contains cone cells, which are responsible for color perception. There are three types:

• S-cones (sensitive to blue),

• M-cones (sensitive to green), and

• L-cones (sensitive to red).

In normal vision, any light that stimulates the M-cones also activates neighboring L and/or S-cones, as their functions overlap.

But in this study, as reported by BBC, the laser was able to stimulate only the M-cones, sending a color signal to the brain that does not occur in natural vision. This means that “Ollo” cannot be seen with the naked eye in the real world without special stimulation.

To verify their experience, each participant adjusted a controllable color dial to match and observe the new color “Ollo.”

🔍 Conclusion:
“Ollo” may not be visible naturally, but this groundbreaking research opens doors to a better understanding of how the brain processes color — and possibly even future treatments for visual disorders.
