We often wonder: What colors can cats see? Can they see only black and white, like cows? or can they see colors like us, like humans? Many people often have different questions related to cats’ eye spectrum.
In this article, we will answer all these questions and explore in detail what colors cats can see. Let’s start by understanding the cat’s eye structure.
Understand the Cat’s Eye Structure
As evident, the eyes are an organ that adjusts the amount of light that goes in and produces continuous images that are quickly relayed to the brain.
Animals’ eye structures, like cats’, are somewhat like ours but with slight differences. Cats have enormous eyes compared to their head size. Unlike humans, who can see 180°, cats have a wider field of view of 200°, making them more likely to see staff behind their backs.
Cats perceive the world differently from humans. Humans have trichromatic vision, i.e., they see the world with a wide range of colors due to their three types of cone photoreceptors, and cats are dichromatic, i.e., they have two types of cone photoreceptors.

How Do Cats See Colors?
Here is a detailed process for how cats’ eyes work and how they see colors:
- Sclera: The white part of the eye.
- Conjunctiva: A thin membrane covering the sclera and the inside of the eyelids.
- Cornea: A clear dome in front of the eye that protects it and lets light in.
- Iris: The colored area of the eye.
- Pupils: Cats have vertically slit pupils that allow light to enter.
- Lens: Behind the iris, it helps focus light.
- Retina: the light-sensitive tissue at the back of the eye.
- Brain: Converts light signals from the retina into images.
The Color Spectrum for Cats
Cats are most sensitive to wavelengths in the blue-violet and greenish-yellow ranges. This allows them to see shades of blue and green quite well. For instance, they can easily distinguish between blue and green objects and see shades within these colors more clearly than others.
Cats have difficulty distinguishing between reds and pinks. These colors may appear more muted or even grayish to them. This is because their dichromatic vision lacks the third cone type humans use to see red and orange hues. Therefore, red toys or objects might not stand out to a cat as vividly as they do to us.
Cat Vision Compared to Human Vision
There are several ways in which cats’ visions are different from ours. Below are the details:
Dichromatic vs. Trichromatic Vision:
Humans have trichromatic vision due to three types of cones that detect red, green, and blue light. This combination allows us to see a broad spectrum of colors. In contrast, cats’ dichromatic vision limits their color perception mainly to the blue and green ends of the spectrum.
Their Color Range:
Humans can see and differentiate between various colors, including those in the red and orange spectrum, which cats cannot perceive. This difference is crucial when considering how cats interact with their environment, choose their toys, and navigate spaces.
How This Affects Cats’ Perception
Cats rely less on color vision than humans and more on their other senses, like smell and hearing, as well as their excellent night vision. Their limited color spectrum means they may not see the full richness of colors in their environment. Still, their vision is well adapted to low light conditions and detecting movement, which is essential for hunting.
Understanding the color spectrum for cats can help pet owners make more informed choices about toys, bedding, and even home decor to create a visually stimulating and comfortable environment for their feline friends. While bright red toys might catch a human’s eye, a cat might be more intrigued by objects in blue or green hues.
Colors That Are Sensitive to Cat
Cats see the world differently than humans do. While humans can see a full spectrum of colors, cats have a more limited range. Here are the colors that cats are most sensitive to:
Blues and Purples
Cats can see blue and purple shades quite well. These colors appear vibrant to them, similar to how humans perceive them. So, toys and objects in blue and purple will stand out to your feline friend.
Greens and Yellows
Cats can also see greens and yellows, but these colors may not appear as bright and distinct as they do to humans. While they can detect these colors, they are less vivid and may blend into other shades.
Grays and Muted Colors
A significant portion of a cat’s vision is in shades of gray. This is because cats are more sensitive to low light levels, allowing them to see well in the dark. As a result, many colors can appear muted and less saturated.
Reds and Oranges
Cats have difficulty distinguishing between reds and oranges, which often appear as gray or brown. Therefore, items in these colors might not stand out much to cats.
How Cats Use Their Vision
Cats have unique vision capabilities tailored to their needs as nocturnal hunters. Here’s an overview of how cats use their vision in various aspects of their lives:
Hunting and Navigating in Low Light:
Cats are crepuscular, meaning they are most active during dawn and dusk. Their eyes are specially adapted to low-light conditions. Cats have many rod cells in their retinas, which are sensitive to dim light.
Detecting Movement:
Cats are highly sensitive to movement, which helps them detect prey. Even slight movements are easily noticed by cats, making them efficient hunters.
Peripheral Vision:
As said earlier, cats have a wide field of view, approximately 200 degrees, compared to humans’ 180 degrees. This peripheral vision helps them detect movement, enhancing their ability to hunt and stay safe from predators.
Depth Perception:
Cats have excellent depth perception thanks to their forward-facing eyes, which provide binocular vision. This depth perception is essential for judging distances accurately when pouncing on prey or navigating their environment.
Close-Up Vision:
While cats have great vision in low light and can see movement well, they are not as adept at seeing things up close. Cats are nearsighted and may have difficulty focusing on objects very close to their faces.
Color Perception:
They see primarily in shades of blue, green, and gray. This limited color vision doesn’t hinder their ability to hunt or navigate since their vision is more adapted to detecting motion and seeing in low light.
Grooming and Social Interaction:
Cats use their vision to communicate and interact with other cats and humans. Eye contact and slow blinking are common ways cats express trust and affection.
FAQs:
1. Can Cats Distinguish Different Shades?
Yes, cats can distinguish different shades, but not as well as humans. Their color vision is limited mainly to shades of blue, green, and gray. They can see variations in these colors but do not perceive the full spectrum humans do.
2. Does a cat’s color vision affect their behavior?
A cat’s limited color vision does not significantly affect their behavior. Cats rely more on their other senses, such as smell, hearing, and their ability to detect movement. Their vision is adapted to their needs as hunters, focusing more on detecting motion and seeing in low light rather than distinguishing a wide range of colors.
3. Can cats see in black and white?
No, cats do not see in black and white. They can see some colors, primarily blues and greens. However, their color vision is not as vivid or varied as that of humans. They see the world in muted tones compared to our colorful perception.
4. Do cats see the same colors as dogs?
Cats and dogs have similar color vision, but there are some differences. Both animals see fewer colors than humans. Cats and dogs mainly see blues and greens, but dogs can sometimes see yellow. Neither can see reds and oranges distinctly, resembling shades of gray or brown.
5. Can cats see in the dark?
Cats cannot see in complete darkness, but they can see much better in low light than humans. Their eyes have many rod cells, which are sensitive to dim light. This adaptation allows them to see well during dawn, dusk, and nighttime, which helps them hunt and navigate in low-light conditions.
