No, is the answer, however, their color vision is quite poor. In the first half of this century scientists were positive that cats were completely color blind and one expert reworked a popular saying with the words: ‘Day and night, all cats see gray.’ That was the persisting attitude in the 1940s, however during the past few decades more measured inquiry has been accomplished and it’s now recognized that cats are able to pick out certain colors, but not, seemingly, with very much finesse.
The reason why earlier experiments neglected to show the existence of cats’ color vision was because in discrimination tests cats rapidly caught on to subtle differences in the stage of grayness of colors and then refused to abandon these clues when they were confronted with two colors of precisely the same degree of grayness. Therefore the exams yielded negative results. Employing more advanced techniques, recent fields of study have been capable in proving that cats
