Scientists claim to have created a never-before-seen color, "olo," by using lasers to stimulate specific retinal cells. Five participants described the color as a saturated blue-green, but emphasized the experience surpasses visual representation. The researchers, from UC Berkeley, stimulated M cones exclusively, unlike natural light. While one expert disputes the novelty, the team believes this "Oz vision" technology could advance understanding of color blindness and vision disorders. The color is unlikely to appear on screens soon.
