Five people view a never-before-seen color called ‘olo’
From Popular Science
The rainbow may be due for an update. A new, high-tech method for displaying color has allowed five test subjects to see a shade beyond the standard human range. The research, published April 18 in the journal Science Advances, is proof-of-concept for a technique that could allow neuroscientists to probe previously un-answerable questions about visual perception. In time, it might even help color blind people experience the full color spectrum, and enable regularly-sighted people to differentiate between hundreds, thousands, or millions of previously undetectable hues.
