Earlier, the American scientist J. Neyts conducted experiments on dogs to find out whether they are able to distinguish colors. He found that, in contrast to the human eye, with three types of cone cells, responsible for the recognition of green, blue, yellow and red, in the eyes of dogs have only two kinds of cones. This means that the dogs distinguish blue and yellow, but do not perceive red and green.
