Scientists have just created a new colour named Olo, which does not exist within the visible spectrum detectable by a normal human eye. In an experiment conducted by scientists from the University of California and the University of Washington School of Medicine, a new colour was generated by using laser light to stimulate only a single type of light-sensitive cone in the human eye—a colour never before seen by human eyes. The possible description of this colour is to imagine it as a hyper saturated bluish-green.
