A group of scientists might have discovered a new color thanks to a unique retina stimulation technique that targeted specific photo receptors in the eye.

In the experiment, researchers directed a laser beam into one eye of each participant. The study involved five individuals — ...

Five individuals participated in the experiment, which involved shooting pulses of visible-wavelength laser light directly into their eyes to stimulate individual photoreceptor cells on the retina.
