No, that is the answer, however, their color vision is very poor. In the first half of this century, scientists were positive that cats are completely colorblind, and one expert paraphrased a popular saying with the words: “Day and night, all cats see grey.” This was the situation going on in the 1940s, but over the last few decades more measured investigations have been done, and it is now recognized that cats are capable of selecting certain colours, though not, it seems, with great subtlety.
The reason previous experiments neglected to show that cats had color vision was that in discrimination tests, cats quickly detected subtle differences in the gray phase of colors and then refused to give up these clues when faced with precisely two shades of colour. The same degree of gray hair. So the tests yielded negative results. Using more advanced techniques, recent fields of study have been able to demonstrate that cats can distinguish between red and green, red and blue, red and gray and green, blue and green, gray and blue, gray and yellow, blue and yellow-grey. Whether they can distinguish between other color pairs is still questionable. For example, one expert believes that they can also distinguish between red and yellow, but other experts disagree.
Whatever the outcome of these investigations, one point is certain: Color isn’t as crucial to cats’ lives as it is to ours. Their eyes are more tuned to see in dim light, as they only need 1/6 of the light that we do to pick out the same details of movement and shape.
