Dalton, a squirrel monkey who used to be red-green colorblind, can now see those colors, thanks to a novel gene therapy treatment. Scientists test his color vision by showing him a circle of red dots within a grey-green background. When Dalton touches the correct location of the red spot, he is rewarded with a drop of juice.
