Hue new? Scientists claim to have found colour no one has seen before

A team of scientists claims to have experienced a new, unnamed color called "olo," achieved by stimulating M cones in people's retinas using lasers. The color, beyond human perception, relies on activating these cones exclusively, which natural light can't replicate. Researchers hope this breakthrough will advance understanding of visual perception and aid in studying conditions like color blindness or retinitis pigmentosa, though its practical applications remain limited due to its niche use.
