A team of scientists from the University of California, Berkeley, have discovered a new colour called Olo, a bright blue-green that the human eye has never seen before. The discovery was achieved by using laser beams to stimulate certain cone cells in the eye's retina, allowing study participants to see this unique colour. So, what should you know about it?
For your information, humans see colour 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 colour, our brain combines all three cone cells to produce colour. 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 unique colours that never existed in nature.
Although this colour 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 colour has the potential to be widely used in the future, especially in visual display technology.
