allowed red-green color blind monkeys to see new colors that they have never seen before. The scientists used a computerized test for human color blindness similar to well-known test books where colored numbers or symbols are hidden in a pattern of dots.

A correct choice was rewarded with a small amount of white grape juice and a positive clinking sound. After a wrong choice, no juice was delivered and a negative ringtone sounded. Like color-blind humans, the monkeys couldn’t distinguish red or green, but after treatment, they passed the test for all colors.
