Scientists have announced the discovery of a new colour, dubbed ‘olo’ - a saturated shade of blue green – only ever seen by five people in the world.
The discovery was made possible using a novel technique called the Oz Vision System, which employed laser stimulation to allow the eye to experience colours that lay outside the normal gamut of colour perception.
According to the study, published in Science Advances, when Oz laser signals were deliberately ‘jittered’ – adjusted by a few microns – subjects reported seeing a ‘blue green of unprecedented saturation, when viewed relative to a neutral grey background.’
