Cats are not completely color blind, but their color vision is limited compared to humans. They see fewer colors, mostly in muted tones of blues, yellows, greens, and grays. Cats have fewer cone cells in their eyes than humans, which means they cannot perceive the full spectrum of colors that people can. They are similar to humans who are red-green color blind, having difficulty distinguishing reds and greens, which may appear as shades of gray to them. Cats rely more on brightness and movement than on color in their vision.
