Cats can see colors, but not in the same way that humans do. They have fewer cones in their eyes than humans, which means they cannot perceive the full range of colors that humans can. The colors that cats can see are more muted and less vivid than what humans see. Cats two color-detecting cones let them see blue-violet and yellow-green wavelengths of light, but not red-orange. Some scientists believe that cats see only blue and gray, while others think they see also see yellow like their canine counterparts. Cats are not good at distinguishing between purple, yellow, and even white. They are inclined more toward blue and green shades. Cats can recognize shades in the grey, blue, and green color palette, and they are masters in the grey undertones. The sun in their world vision is green and blue. Cats are not able to perceive red, orange, and brown colors. Knowing what colors cats can see can help cat owners make good choices for their pets, such as choosing toys that are yellow and blue instead of red.
