A group of scientists from the University of California, Berkeley have successfully discovered a new color known as Olo, a bright blue-green color that has never been seen by the human eye naturally. This discovery was achieved by using a laser beam to stimulate certain cone cells in the retina of the eye and allowed participants involved in the study to see this unique color.
In theory, humans see color through three types of cone cells in the eye, namely L (red), M (green), and S (blue). S responds to blue light (short), M to green (medium), and L to red (long). When we see color, our brain processes a combination of all three cone cells to produce color. However, in a recent discovery, scientists managed to stimulate only the M (green) cone cells without involving other cone cells. As a result, participants were able to see a unique color that never exists in nature.
Although this color is not yet widely used in a natural context, this discovery has opened up new potential in the fields of science, technology, and visual display. Scientists also believe that this unique color has the potential to be widely used in the future, especially in visual display technology.
