Is this really true that cats are colour blind?

No, the answer is, but their color vision is quite poor. In the first half of this century, scientists were positive that cats were completely color blind and an expert worked a popular saying with the words: 'Day and night, all cats look gray. "It was the attitude persists in the 1940s, but during the past few decades has been more measured study, and it is now recognized that cats are able to select specific colors, but not, apparently, with much finesse. reason that previous attempts have failed to show the existence of cats' Color vision was because of discrimination test cats quickly caught on subtle differences in the phase grayness of color and then refused to abandon those tracks when they were confronted with two colors exactly the same degree of grayness. Therefore samples showed negative results. employing more advanced techniques, recent areas of study has been able to prove that cats can tell between red and green, red and blue, red and gray, green and blue, green and gray, blue and gray, yellow and blue and yellow and gray. Whether they can distinguish between other pairs of colors are still in question. For example, consider an expert that they can distinguish between red and yellow, but other experts disagree. Whatever the outcome of these investigations one point is certain: Color is not crucial in the lives of cats, as it is in ours. Their eyes are much more tuned to see in dim light, where they only need 1 / 6 of the light that we do to pick out the same information about movement and form.Write text or a website address or translate a document.CancelListenEnglish to German translationNo, the answer is, but their perception of color pretty badly. In the first half of this century, scientists were positive that cats are completely colorblind and an expert was a popular saying with the word "revised" day and night all cats are gray. "It was the persistent attitude of the 1940s, has undergone in recent decades, but more measured request and it is now recognized that the cat is able to make certain colors, but apparently not with much finesse.
The reason why previous attempts have failed to show the existence of cat color vision, because tests of discrimination cats quickly cast on subtle differences in the stage of the colors were captured and then refused to leave these instructions when they were confronted with two colors exactly the same level of gray. Therefore, the tests showed negative results. With more advanced techniques that were recently specialization to prove that cats can be gray between red and green, red and blue, red and gray, green and blue, green and gray, blue and gray, yellow and blue and say yellow . Whether it is necessary to distinguish between other pairs of colors are still in question. One expert believes that the distinction between red and yellow, but other experts agree.
Whatever the outcome of these investigations One point is certain: Color is not in the lives of cats crucial, since in our. Her eyes are so much better in low light where it needs only 1 / 6 of the light that we use to select the same data movement and shape to be seen.
