The color, dubbed olo, is described as an intensely saturated teal. Researchers say it might have applications in understanding color blindness

For the first time, humans might have glimpsed the rainbow of color that lies just beyond our sight – including a "blue-green of unprecedented saturation". You've never seen it before because you can't.

Researchers from the University of California, Berkeley have announced the discovery of a color never before seen by the human eye. Through a new study, published in Science Advances, researchers used a pulsing laser on study participants to stimulate a part of the eye.
