Humans have three types of cone cells in the back of the
eye to differentiate color. Some react to blue, some to
green and some to red. The cones do their work by responding
to the difference in wavelength of the incoming light. Such
vision is known as trichromatic. In this new effort, the
researchers have found a way of fooling the brain into
seeing as if there were a fourth type of cone, by wearing
glasses with two types of filters. The result is tetrachromatic
vision.
Which seems to be different from the google hit I got for colors never seen:
