When it comes to understanding how cats perceive the world around them, their sense of sight is a topic of great interest. As cat owners, we often wonder: What colors can cats really see?
Cats‘ vision is quite different from that of humans, and their ability to see colors is limited in comparison. While a cat’s sense of sight is adapted to its predatory lifestyle, their ability to detect colors isn’t as sharp as ours.
In this article, we’ll delve into the science of cat vision, focusing on what colors cats can see, how they perceive their environment, and how this influences their behavior and interactions with us.
What Colors Can Cats Really See?
Understanding the Basics of Cat Vision
To understand how cats see colors, it’s important to first understand the mechanics of their vision. Just like humans, cats have eyes that work in conjunction with their brain to process visual information.
However, cats’ eyes are adapted to their nocturnal and predatory nature, allowing them to see in low light and detect movement more effectively than humans. They have a larger proportion of rod cells (responsible for vision in low light) compared to cone cells (responsible for color vision).
Rods vs. Cones
Rods are responsible for vision in dim light, helping cats to see in dark environments. Cats have a greater number of rod cells in their retinas compared to humans, which allows them to see better in the dark.
Cones, on the other hand, are responsible for detecting color and detail in brighter light conditions. Humans have three types of cones, which allow us to perceive a full spectrum of colors. Cats, however, have fewer cones and are limited in the range of colors they can detect.
The Role of the Tapetum Lucidum
Another key feature of a cat’s vision is the tapetum lucidum, a reflective layer behind the retina that helps cats see in low light. This layer reflects light that passes through the retina back into the eye, allowing the cat to use it again and enhance its ability to see in dim conditions.
This is why cats’ eyes seem to glow in the dark—they are utilizing the light that comes into their eyes more effectively than humans can.
What Colors Can Cats See?
Now that we understand the basics of a cat’s vision, let’s address the primary question: What colors can cats see?
Cats are dichromatic, which means they have only two types of cones in their eyes compared to humans, who are trichromatic (three types of cones). The two types of cones in cats’ eyes allow them to see a limited range of colors.
Based on scientific studies, including research on cat vision, we know that cats primarily perceive blue and green colors. They have difficulty distinguishing between reds, pinks, and oranges, and these colors likely appear as shades of gray or a muted color.
Here’s a breakdown of how cats likely perceive different colors:
1. Blue and Green
Cats can perceive blue and green hues quite well. Shades of blue, from light blue to dark navy, are visible to them, and they can distinguish different shades of green as well. This means that objects in blue or green will stand out to a cat and can be more easily identified in their environment.
2. Red and Orange
Red and orange are colors that cats have a harder time seeing. These hues likely appear as a shade of gray or brownish tone. For example, a bright red toy might appear dull or less vibrant to a cat, and an orange object may seem similar to yellow or brown in their vision.
3. Yellow
Cats can see some yellow, though it’s not as vivid as the yellow that humans perceive. Yellow objects are likely visible but may appear somewhat muted or less vibrant in comparison to what we see.
4. Purple
Because purple is a combination of blue and red, cats can perceive it as a shade of blue. They may not see the full vibrancy of purple as humans do, but they can likely detect the blue tones that make up the color.
5. Gray and Brown
Cats likely see shades of gray, brown, and muted colors more clearly than other colors. These neutral tones are well within their visual spectrum, and they are likely to see these colors with good contrast, making them easy to distinguish.
6. Pink
Like red and orange, pinks are difficult for cats to distinguish. Pinks might appear as dull shades of gray or light brown, making them less noticeable to cats than they are to humans.
How Do Cats Perceive the World?
Given their limited color spectrum, cats likely experience the world in a way that is much different from humans. While humans see a vibrant and colorful world full of reds, greens, blues, and yellows, cats likely see a more muted and subdued environment, with shades of blue, green, gray, and brown being more prominent.
Despite their limited color perception, cats are still highly efficient at detecting movement. Their eyes are designed to pick up on even the smallest motion, especially in low light conditions, which makes them excellent hunters. This ability to detect movement is far more important to cats than distinguishing between a wide range of colors.
In terms of contrast, cats are highly sensitive to differences in light and dark, which helps them see in dim environments. For instance, a cat might not be able to distinguish a red ball from a green one, but they can easily spot the ball moving across the floor, regardless of its color.

Why Can’t Cats See Colors Like Humans?
The reason cats have a limited ability to perceive colors comes down to the differences in the number of cone cells in their retinas.
Humans have three types of cones that allow them to see a full spectrum of colors: red, green, and blue. This is why we are able to differentiate between many colors, including red, yellow, purple, and more.
Cats, on the other hand, only have two types of cones, which means they can only perceive blue and green wavelengths of light effectively.
The red end of the spectrum is not well represented in their vision, making red and orange objects appear more muted or indistinct.
This limited color vision is not a disadvantage for cats, however. Their ability to see well in low light conditions, detect motion, and focus on high-contrast objects is more suited to their needs as predators.
Cats primarily rely on these visual capabilities for hunting and navigating their environment, rather than on color perception.
The Role of Color in a Cat’s Life
Although cats can’t see colors in the same way that humans do, this doesn’t mean they are impaired when it comes to their ability to interact with their environment.
The colors that they do see—primarily blues, greens, and shades of gray and brown—are enough for them to function effectively as hunters and companions.
Toys and Interaction
When selecting toys for your cat, it’s important to keep their color perception in mind. Bright blue or green toys will likely be more appealing to them, as these colors are easier for them to distinguish. Red, orange, and pink toys may not stand out as much, but cats are often attracted to movement, texture, and scent, so a toy’s color isn’t always the primary factor in its appeal.
Identification of Objects
Cats may not identify objects by their color, but they use their excellent sense of sight, hearing, and smell to interact with their environment. For instance, a cat might not recognize a red ball as a distinct object based on its color, but it will identify the ball based on its shape, texture, and scent.
Importance of Movement
One of the key reasons cats do well with limited color vision is their superior ability to detect motion. Their eyes are specially adapted to notice even the smallest movement in low-light conditions, which is crucial for spotting prey. This ability far outweighs the need for detecting a wide range of colors in their environment.
FAQs
Can cats see in the dark?
While cats cannot see in total darkness, their eyes are adapted to see very well in low-light conditions. Their larger number of rod cells allows them to detect movement and navigate in dim lighting, which is why they are excellent hunters at dawn or dusk.
What colors do cats see the best?
Cats can see blue and green colors the best. These are within the range of colors they can detect clearly, while red, orange, and pink tend to appear dull or muted.
Do cats see the same colors as dogs?
No, dogs also have limited color vision, but they see fewer colors than cats. Dogs are believed to be colorblind in the sense that they can only distinguish between shades of blue and yellow. Cats, on the other hand, can see blues, greens, and some shades of gray.
How does a cat’s vision affect its hunting behavior?
A cat’s vision is adapted to detect movement rather than rely on color. This ability to spot movement in low light helps them hunt effectively, as they can notice the smallest shifts in their environment, such as a mouse moving in the shadows.
Can cats see bright colors like neon?
Neon colors are likely very difficult for cats to see. Bright colors such as neon pink or neon green may appear more muted or pale to them, as their eyes are not able to fully perceive these wavelengths of light.
