A Groundbreaking Revelation in Color Perception

Imagine a color so stunning that it exists just beyond the reach of human sight! A team of daring scientists from the United States has proposed the existence of a totally new color, whimsically named "olo," which can only be seen with technological assistance.

How Is Olo Revealed?

Using a unique contraption whimsically dubbed after the Wizard of Oz, researchers fired laser pulses directly into the eyes of subjects to unveil this extraordinary hue. While it remains invisible to the naked eye, those lucky enough to catch a glimpse describe olo as reminiscent of a vibrant teal.

Scientific Breakthroughs that Challenge the Norm

Professors from the University of California, Berkeley and the University of Washington School of Medicine shared their fascinating findings in the journal Science Advances. They introduced a technique called "Oz" to harness the capabilities of the human eye, enabling viewers to experience this color beyond perception.

The Science Behind Color Perception

Human color perception relies on three types of cone cells in our retinas—S cones for blue, M cones for green, and L cones for red. Signals from these cones travel to the brain's visual cortex, allowing us to interpret colors. However, M cones often overlap with others, limiting our ability to appreciate shades like olo unless using specialized technology.

The Quest for Olo: How It All Began

Curious about what it would be like to stimulate only the M cones—those sensitive to green light—professor Ren Ng joined forces with Austin Roorda, a creator of the Oz technology. This groundbreaking device targets individual photoreceptors using laser light to reveal unseen colors.

Is Olo Truly New?

While the shade might be novel to humanity, it has always existed in the spectrum outside our visible range. However, from a sociolinguistic perspective, naming it may signify its newfound relevance in conversation.

Limited Viewers: Who's Seen Olo?

So far, only five individuals—four men and one woman, all with normal color vision—have had the privilege to view olo. Among them were researchers involved in the study who had no prior knowledge of its purpose.

Describing the Unseeable

Those fortunate enough to experience olo describe it as a deeply saturated teal, unlike anything they've encountered before. Roorda noted it as a "blue-green color of unparalleled saturation," asserting that even the most vibrant natural colors pale in comparison.

Can This Technology Benefit the Color Blind?

Researchers are now contemplating whether the Oz technology could aid those with color blindness. While challenges exist in miniaturizing the technology for practical use, there's hope it could directly stimulate the appropriate cones based on the specific type of color blindness.

Exploring Color Perception in Humans and Beyond

The experience of color is complex, involving physical, neurological, and social components. Different species perceive color in unique ways; for example, mantis shrimp can see 12 color channels, while dogs are limited primarily to shades of yellow and blue.

The Future of Color Discovery

As we delve deeper into the realms of color perception, the fascination with olo and its availability remains a tantalizing prospect. What other spectacular shades lie hidden, waiting to be unveiled to the human eye?
