Only 5 People in the World Have Seen the Color “olo”, Created with a Laser That Tricks the Retina

Have you ever imagined seeing a color that no one else in the world can see? Scientists at the University of California, Berkeley achieved the impossible: creating a new color for the human eye. The experiment, conducted using precision lasers and advanced eye tracking, allowed five volunteers to see a shade that simply does not exist in nature or on screens, according to the MSN website.

How Is It Possible to See a New Color?

Through the Oz Vision platform, researchers used microdoses of laser to activate only the M cones in the retina (sensitive to green light), without interfering with the L (red) or S (blue) cones. This selective activation tricked the brain, creating a new visual perception: a color dubbed “olo”, an ultra-saturated blend of green and blue — impossible to describe or represent.

“It’s a sensation of seeing something completely outside of what we know as visual reality,” reported one of the volunteers.

At the top of the world at 5,600 meters in the Atacama Desert, an unprecedented telescope begins to operate and could rewrite everything we know about the cold universe, the Big Bang, and the origin of galaxies.

Researchers were excavating in Peru when they found a stone structure over 4,000 years old, and upon analyzing the site, they discovered an advanced astronomical observatory that could change everything we know about ancient civilizations in the Americas.

Before the arrival of the cold, a low-pressure system could dump more than 100 mm of rain in western Rio Grande do Sul, bringing hail, lightning, and strong gusts, and abruptly changing the weather in Southern Brazil.

What Is the Oz Vision System?

The revolutionary technology combines:

Ultra-thin lasers
High-precision moving mirrors
Real-time optical sensors
Eye tracking software (nicknamed Wizard)

With it, each cone of the retina can be individually stimulated, even with the eye in constant motion.

Why Is the Discovery So Important?

The color “olo” cannot be printed, displayed on screens, or described with words
It is visible only with direct stimulation of the retina
It could represent a new sensory dimension for humans

In tests, participants were exposed to all colors of the visible spectrum and could not compare “olo” to any of them.

Future: Colors for the Colorblind and Beyond

The technique also has the potential to create “virtual cones”, which could allow colorblind individuals to see a wider range of colors. In tests with primates, scientists have already succeeded in expanding color perception — and hope for similar results in humans.

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

BRICS is preparing a payment system inspired by the Brazilian PIX that will allow direct transactions between countries using national digital currencies without relying on the dollar or Western banks as intermediaries.
