A team of scientists has announced the discovery of a new color that no one has ever seen before. This colour, described as a vibrant shade of blue-green, was experienced during an unusual experiment that used lasers.
The research team, based in the United States, asked participants to look into a special device called Oz. This device, which contains mirrors and lasers, stimulates certain cells in the eye called cone cells, responsible for color vision. Participants were exposed to laser pulses that specifically targeted one type of cone cell in the retina. The researchers believe that this created a color experience that cannot be found in the natural world.
According to the, Professor Ren Ng from the University of California, shared his excitement about the discovery of “olo.” He described it as “more saturated than any color that you can see in the real world.” To help illustrate the experience, he compared it to seeing baby pink all of your life and then encountering a much more intense shade of pink—like a whole new color.
The experiment involved five participants who all had normal color vision. Each participant stared into the optical device while laser beams were directed into one of their eyes. During this process, they reported seeing the colour “olo,” and to ensure accuracy, they adjusted a color dial until it matched what they perceived as olo.
While this discovery has generated excitement among researchers, some experts express caution. Professor John Barbur, a vision scientist from City St George’s, University of London, stated that while the experiment was a significant technological achievement, whether it truly represents a new color is still debatable. He explained that everyone’s perception of colour can vary based on how their eyes work.
The implications of this discovery could extend beyond just finding a new color. The research team hopes to explore how these findings might help people with color blindness, enabling them to distinguish colors more effectively.
