There is a blue-green so saturated that you can only try to imagine it, but not see it... Except by passing under the astonishing machine at the University of Berkeley (United States). Based on a precise mapping of the location of each of the three types of cones in a retina, this device was able to selectively stimulate certain ones in a way that would be impossible to achieve under natural conditions. This new strategy, called Oz, could allow colorblind people to regain the perception of certain colors.

By stimulating just one of the three types of cones in our retina, researchers have succeeded in making us perceive a new color that is usually outside the spectrum of human perception.
We perceive color thanks to specialized cells in our retina, the cones.
