Researchers at the University of California have identified a unique color experience, dubbed 'Olo,' perceived through targeted retinal stimulation. While not a new color in the traditional sense, this discovery, published in Science Advances, highlights the complexities of human vision.
The experiment involved selectively stimulating the M cones in the retina using a laser-based device. Five participants with normal color vision reported perceiving a color sensation described as a blue-green hue. This was achieved using a device that employs mirrors, lasers, and optical components to precisely control light exposure to the retina.
The technology used to elicit this perception, while not creating a new color pigment, offers potential for understanding and addressing visual impairments. The exploration of retinal response opens avenues for investigating the intricacies of human vision and potential therapeutic interventions.
