Teal is a greenish and bluish shade. But what’s going on if it was more?
Imagine a dynamic sarcelle more saturated than any color you have ever seen in the natural world.

A color sample approaching a less saturated “olo”, a blue-green color. It can only be seen in a specialized laboratory which uses machines to stimulate only a specific subset of photoreceptors in the human eye.

This is how a few rare people describe a new color called “olo”. The shadow was only seen by a handful of scientists from the University of California in Berkeley in an article published in the journal Scientific advances last month.
The view is so exclusive because olo does not exist in nature. It cannot be found among the paint boxes. On the contrary, Olo is created thanks to the intervention of prudent computers and lasers.
The research team was led by Vision Scientist Austin Roorda and computer scientist Renown. Together, they have found a method to stimulate only the retina cones, which does not occur outside a specialized laboratory. The experience is called Oz Vision, going back to the classic film The Wizard of Oz.
NG hopes that the technology used brings us closer to Dorothy’s Technicolor entry into the country of origin of OZ – whether by studying diseases that lead to blindness or by finding ways to ensure that people with daltonism see a complete color.
