Scientists from UC Berkeley and the University of Washington claim to have discovered a new color called 'olo', a saturated blue-green visible only through laser stimulation. The study, published in Science Advances, describes how five participants perceived this color using a technique named after the Emerald City. While some researchers celebrate the findings, others contest the claim, arguing that 'olo' is merely a more saturated green. The study aims to explore visual perception and could have implications for understanding color blindness. Teljes cikk (Euronews.com)
