olo new color yolo stuart semple

Researchers at the University of California, Berkeley, have discovered a new color called "olo" that cannot be seen under normal conditions. The color, described as a highly saturated blue-green, was perceived by five human subjects during tests using a complex laser system and custom software named Oz. The team published their findings in *Science Advances* on April 18, explaining that olo results from stimulating only the medium-wavelength cone cells in the retina, a feat not possible with natural light. British artist Stuart Semple has since created a physical paint called YOLO, claiming it is the closest approximation to this elusive color, priced at $10,000 per 150ml bottle.
