Scientists Unveil 'Olo,' a Color Outside Human Vision's Natural Range

Using advanced laser technology, researchers have stimulated M-cones in the retina to create a hyper-saturated blue-green hue, sparking debates on its novelty and potential applications.

Using a new technique called “Oz,” scientists at UC Berkeley can trick the eye into seeing images, videos and even a brand new color — a profoundly saturated peacock green that they named “olo.”
Scientists at the University of California say the new colour — which they've named "olo" — is a blue-green hue with an "unprecedented saturation."

Overview

  • The Oz system uses adaptive optics and laser precision to stimulate M-cones in the human retina, producing a novel color named 'Olo.'
  • Study participants described Olo as a hyper-saturated blue-green hue, unlike any color previously perceived within the human visual spectrum.
  • The effect is temporary, visible only during laser stimulation in a peripheral, fingernail-sized area of the retina.
  • The research, published in *Science Advances*, involved scientists from UC Berkeley and the University of Washington, marking a breakthrough in vision science.
  • Future applications may include therapies for color blindness and vision augmentation, though the technology remains limited by high costs and technical constraints.
