SCIENTISTS HAVE DISCOVERED A "JAW-DROPPING" NEW COLOUR – BUT YOU CAN'T SEE IT

Summary from the TLDR Design newsletter

U.S. scientists have discovered a new color, "olo," by using lasers to stimulate only the medium-wavelength cones in the retina—something not possible naturally. Described as a vivid blue-green, olo can't be shown on screens or seen without special equipment, making it a unique perceptual experience. Though its status as a "real" color is debated, the find offers new insight into how we see and understand color.
