What colors do cats see best? Cats have dichromatic vision, meaning they only have two types of cones in their retinas, which are sensitive to short-wavelength (blue) and middle-wavelength (green) light. This means that cats cannot see red, orange, or purple. The world appears to them in shades of blue, green, yellow, and gray.
This type of color vision is common in mammals and is thought to have evolved because it is advantageous for hunting in low-light conditions. Cats are able to see better in the dark than humans, and their dichromatic vision helps them to distinguish between prey and predators.
While cats cannot see the full range of colors that humans can, they are still able to see a wide variety of colors. This is because their brains are able to fill in the gaps in their color vision by using information from other senses, such as smell and touch.
What Colors Do Cats See Best?
Cats have dichromatic vision, meaning they only have two types of cones in their retinas, which are sensitive to short-wavelength (blue) and middle-wavelength (green) light. This means that cats cannot see red, orange, or purple. The world appears to them in shades of blue, green, yellow, and gray.
- Cone cells: Cats have fewer cone cells than humans, which are responsible for color vision.
- Retina: The retina is the light-sensitive tissue at the back of the eye that contains the cone cells.
- Wavelength: The wavelength of light determines its color. Shorter wavelengths are blue, and longer wavelengths are red.
- Dichromacy: Dichromacy is a type of color vision deficiency in which people can only see two colors.
- Vision: Cats have excellent night vision, but their color vision is not as good as humans.
- Hunting: Cats’ dichromatic vision is thought to have evolved because it is advantageous for hunting in low-light conditions.
- Prey: Cats are able to distinguish between prey and predators, even in low light, thanks to their dichromatic vision.
- Color perception: Cats can still see a wide variety of colors, even though they cannot see the full range of colors that humans can.
Cats’ dichromatic vision is a fascinating example of how animals have evolved to adapt to their environment. While cats cannot see the full range of colors that humans can, their vision is still well-suited for their needs.
Cone cells
Cone cells are specialized cells in the retina that are responsible for color vision. Humans have three types of cone cells, which are sensitive to short-wavelength (blue), middle-wavelength (green), and long-wavelength (red) light. Cats, on the other hand, only have two types of cone cells, which are sensitive to short-wavelength and middle-wavelength light. This means that cats are dichromats, which means they can only see two colors. The world appears to cats in shades of blue, green, yellow, and gray.
The fact that cats have fewer cone cells than humans has a significant impact on their color vision. Cats are not able to see red, orange, or purple. They also have difficulty distinguishing between shades of green and red. However, cats are able to see better in low-light conditions than humans, and their dichromatic vision is thought to be advantageous for hunting in low-light conditions.
The study of color vision in cats has helped us to better understand the evolution of color vision in mammals. It has also helped us to develop new treatments for color blindness in humans.
Retina
The retina is a thin layer of tissue that lines the back of the eye. It contains millions of light-sensitive cells called photoreceptors, which convert light into electrical signals that are sent to the brain. The retina is responsible for our ability to see, and it plays a vital role in our perception of color.
Cats have a different type of retina than humans. They have fewer cone cells, which are the type of photoreceptor that is responsible for color vision. This means that cats are dichromats, which means they can only see two colors. The world appears to cats in shades of blue, green, yellow, and gray.
The type of retina that a cat has has a significant impact on its ability to see color. Cats are not able to see red, orange, or purple. They also have difficulty distinguishing between shades of green and red.

The study of the retina has helped us to better understand the evolution of color vision in mammals. It has also helped us to develop new treatments for color blindness in humans.
Wavelength
The wavelength of light is an important factor in determining the color that we see. Shorter wavelengths of light appear blue, while longer wavelengths of light appear red. This is because the human eye has three types of cone cells, which are sensitive to different wavelengths of light. The short-wavelength cone cells are sensitive to blue light, the middle-wavelength cone cells are sensitive to green light, and the long-wavelength cone cells are sensitive to red light.

The vision of cats is a complex and fascinating subject. By understanding the unique visual adaptations of cats, we can better appreciate the challenges and advantages that they face in their environment.
Hunting
Cats are obligate carnivores, meaning that they must eat meat to survive. They are also crepuscular, meaning that they are most active at dawn and dusk. This means that cats need to be able to see well in low-light conditions in order to hunt for food.
Cats’ dichromatic vision is thought to have evolved because it is advantageous for hunting in low-light conditions. Dichromatic vision means that cats can only see two colors, blue and green. This may seem like a disadvantage, but it actually gives cats an advantage over humans in low-light conditions. This is because the rods in cats’ retinas, which are responsible for low-light vision, are more sensitive to blue and green light than they are to red light. This means that cats can see better in low-light conditions than humans can.
In addition to their dichromatic vision, cats also have a number of other adaptations that help them to see well in low-light conditions. These adaptations include large pupils, which allow more light to enter the eye, and a reflective layer behind the retina, which helps to amplify the light that does enter the eye. These adaptations, combined with their dichromatic vision, give cats excellent night vision.
The ability to see well in low-light conditions is essential for cats’ survival. It allows them to hunt for food and avoid predators. Dichromatic vision is a key component of cats’ ability to see well in low-light conditions, and it is an important adaptation that has helped cats to survive in the wild.
Prey
