What Colors Do Dogs See Best: A Comprehensive Guide

Dogs are known for their keen senses, including their exceptional sense of smell and hearing. However, when it comes to vision, many pet owners wonder what their furry friends can actually see. Understanding how dogs perceive color can help you provide a more enriched environment for your dog and even improve communication with them. While humans see the world in a wide range of colors, dogs have a more limited spectrum of colors that they can distinguish. In this comprehensive guide, we will explore how dogs see color, which colors they can see best, and which ones they struggle to perceive.



Dogs are known for their incredible sense of smell and hearing, but what about their vision? Have you ever wondered if dogs see the world in the same way we do? While our eyes have three types of color receptors or cones, dogs only have two, which means that their color vision is different from ours. In this comprehensive guide, we’ll explore how dogs see colors, the types of colors they can see best, and the colors that they struggle to perceive. We’ll also provide tips on how to get your dog’s attention through visual cues. Whether you’re a dog owner or simply fascinated by animal vision, this guide will help you better understand the colorful world of dogs. So, let’s dive in!

How Dogs See Color

Rods and Cones in Dogs’ Eyes

Photoreceptor cells are the key components of a dog’s visual system that enable them to perceive light and images. Dogs have two types of photoreceptor cells, known as rods and cones, located in their eyes.

Rods play an essential role in low-light vision and detecting motion. These cells contain a pigment called rhodopsin, which is sensitive to light wavelengths in the blue-green spectrum. This sensitivity allows dogs to see better than humans in dimly lit environments, making them ideal for hunting and tracking prey in the evening or early morning hours.

On the other hand, cones are responsible for color vision and high acuity. Dogs have fewer cone cells than humans, which means they have limited color perception compared to us. Their cones are also less sensitive to low levels of light, making it harder for them to distinguish colors in poorly lit conditions.

Overall, dogs’ photoreceptor cells contribute significantly to their visual abilities and play a crucial role in their daily lives. Understanding how these cells work can help owners provide better care and ensure their pets’ safety by avoiding activities in low-light conditions where dogs may struggle to see.

Spectra and Wavelengths

Spectra and Wavelengths

To understand how dogs see color, we need to delve into the world of spectra and wavelengths. The visible light spectrum is made up of a range of colors, from red to violet, that we can see with our eyes. Dogs, like humans, have photoreceptor cells called cones in their eyes that allow them to perceive these different colors.

However, while humans have three types of cones that allow us to see a wide range of colors, dogs only have two types of cones. This means that their color perception is not as acute as ours. In fact, dogs are considered dichromatic, meaning that they can only see two primary colors – yellow and blue – as well as shades of gray.

But what does this have to do with spectra and wavelengths? Well, each color in the visible light spectrum has a different wavelength. Red has the longest wavelength, while violet has the shortest. Dogs’ eyes are more sensitive to shorter wavelength light, which is why they can see shades of blue and violet better than they can see green, yellow, or red.

It’s important to note that even though dogs can’t see all the colors that humans can, they still rely on color perception for various tasks. For example, certain bright colors can catch a dog’s attention, making them useful for toys or training tools. Additionally, some dogs are trained to detect particular colors, such as red, when searching for objects or people.

In conclusion, understanding spectra and wavelengths is crucial to understanding how dogs see color. While dogs can’t see all the colors that humans can, they still rely on color perception for various tasks and can see shades of blue and violet better than other colors due to their sensitivity to shorter wavelength light.

Colors That Dogs Can See

Yellow and Blue

Yellow and Blue:

Dogs can see chromatic colors, which means they can perceive a range of hues just like humans. However, their vision range is limited compared to ours. Dogs have two types of photoreceptor cells in their eyes called cones, which allow them to see color. Humans have three types of cones, while dogs have only two. This means that dogs are dichromatic, and their color perception is less complex than humans.

Yellow and blue are two colors that are highly visible to dogs. They can differentiate between shades of yellow and blue much better than other colors. Yellow appears as a bright, vibrant color to dogs, while blue is seen as a darker shade. This is because these colors fall within the middle of the spectrum of visible light and have wavelengths that are not too long or too short for dogs to detect.

One example of how this can be useful is when playing fetch with a yellow or blue ball. The contrast between the ball and the surrounding grass or dirt makes it easier for the dog to locate the ball. Additionally, yellow and blue toys or accessories can help you get your dog’s attention when training or communicating with them.

In conclusion, yellow and blue are two chromatic colors that dogs can see well. While their vision range may be limited, understanding which colors are most visible to dogs can help us interact and communicate with them more effectively.

Violet and Gray

Violet and Gray

When it comes to color perception, dogs see the world quite differently from humans. While humans have trichromatic vision – meaning we can see the full spectrum of colors – dogs only have dichromatic vision. This means they can only see shades of blue and yellow, as well as some grays. This also means that they cannot see pure colors such as red, green, or orange.

Violet and gray are two colors that fall into the category of achromatic colors for dogs. Achromatic colors are those without any hue, such as black, white, and gray. Out of these three colors, gray is the one that dogs can perceive the best. However, this doesn’t mean that they see it as a neutral color like we do. Instead, they see it with a slightly blue or yellow tint, depending on the individual dog’s vision range.

As for violet, it falls into the low vision range for dogs. This means that they struggle to see it and may not even perceive it at all. Violet appears very similar to blue or gray to a dog, making it difficult for them to distinguish between the colors.

However, just because dogs may not see these colors as vibrantly as we do, it doesn’t mean they don’t notice them at all. Dogs rely heavily on their sense of smell and hearing, and often use visual cues as secondary sources of information. Therefore, even though they may not be able to differentiate between violet and blue, they can still use the contrast between these colors to identify objects and determine distances.

In conclusion, while violet and gray may not be the most exciting colors for dogs, they still play an important role in their visual perception. Understanding how dogs see these colors can help us better understand their overall vision and how they interact with their environment.

Colors That Dogs Struggle to See


Green is considered a muddy color for dogs, appearing similar to yellow. This is because dogs have limited color perception, with only two types of cones in their eyes compared to humans’ three. The cones are the photoreceptor cells responsible for color vision and are sensitive to different wavelengths of light.

Dogs’ green color perception is not as developed as humans’, and they may have difficulty distinguishing between green and yellow hues. For example, grass and foliage may appear similar in color to dogs, making it challenging to spot prey or toys hidden among the greenery.

Interestingly, some dog breeds, such as the Australian Shepherd, have a higher number of cones, allowing them to see more colors than other breeds. However, even these breeds may still struggle with green tones.

It’s important to keep in mind that dogs rely more on brightness and contrast rather than color when detecting objects. Therefore, when training or playing with your dog, it can be helpful to use high-contrast toys or treats to grab their attention.

In summary, while green may appear muddy and similar to yellow for dogs, it’s not a significant concern as dogs do not perceive color in the same way humans do. Instead, focus on using brightness and contrast to help your furry friend easily identify objects.

Red and Orange

Red and Orange

Dogs have a difficult time seeing red and orange due to their limited color perception. These colors appear as dull brownish-gray or dark shades, making them blend in with their surroundings.

This is because dogs have only two types of color receptors, whereas humans have three. The two receptors allow dogs to distinguish between blue and yellow, but they struggle to differentiate between red and green. As a result, red and orange can appear murky or grayish to dogs.

Interestingly, some studies suggest that dogs may be able to see some shades of red, but not as vividly as humans do. For example, a bright red toy may appear much less vibrant to your dog than it does to you.

This limited ability to see certain colors has implications for dog toys, clothing, and accessories. If you want to buy your dog a toy, it’s best to choose one that is blue or yellow instead of red or orange. This will make it easier for your dog to locate the toy and play with it.

In conclusion, while dogs can see some shades of red and orange, these colors appear dull and blend in with their surroundings. It’s best to choose toys and other items for your dog in colors that are easier for them to distinguish.

How to Get the Attention of a Dog

Contrast and Brightness

One of the most effective ways to get a dog’s attention is through visual cues. Dogs are highly responsive to contrast and brightness, so it’s important to use these elements when trying to grab their attention.

Contrast refers to the difference between two colors or shades. When there is a high level of contrast, it creates a strong visual signal that stands out from the surrounding environment. This can be particularly effective when using toys or treats to get a dog’s attention. For example, a red ball on green grass provides a high level of contrast, making it stand out and catch a dog’s eye easily.

Brightness, on the other hand, refers to how much light is reflected off an object. Bright objects are more likely to attract a dog’s attention because they stand out from those that are dull or dark. For instance, a shiny metal bowl will reflect more light and attract a dog’s attention more than a plain plastic one.

Visual cues that utilize contrast and brightness can be very effective in training your dog. For example, if you’re teaching your dog to come when called, you could wear a brightly colored shirt or hold a bright toy to help get their attention. Similarly, if you’re trying to teach them to sit, you could use a contrasting background to help them focus on you.

Overall, understanding the importance of contrast and brightness as attention grabbers for dogs can significantly improve your communication with them. By utilizing these visual cues, you can enhance your training sessions and build a stronger bond with your furry friend.

High Saturation

High Saturation

Dogs see colors differently from humans, and their visual system is more sensitive to certain features such as brightness and contrast. However, they also have a limited color perception range that affects how they respond to different hues and shades.

One aspect that can catch a dog’s attention is high saturation, which refers to the intensity or purity of a color. In other words, the more saturated a color is, the more vivid and distinct it appears to the viewer. This is because the color contains less white light and more of its own hue, making it stand out from the surroundings.

When it comes to dogs, high saturation colors can be a useful tool for training, playing, or signaling. For example, if you want your dog to fetch a toy or follow a command, you can use a bright red or blue object that contrasts with the grass or floor. The same applies to agility courses or other activities where you need to guide your dog through obstacles or paths.

However, not all colors have the same effect on dogs, and some may even cause confusion or discomfort. For instance, neon colors or patterns that are too busy or flashy could overwhelm a dog’s senses and distract them from the task at hand. Also, some dogs may have different preferences or reactions depending on their breed, age, or personality.

Therefore, when choosing high saturation colors to interact with your dog, it’s essential to consider their individual characteristics and needs. You can experiment with different hues and tones to see which ones they respond best to, and adjust the intensity or frequency accordingly. By doing so, you can create a positive and enjoyable experience for both you and your furry friend.

In conclusion, high saturation can be an effective way to get your dog’s attention and improve their visual experience. By using vibrant colors and distinctive hues, you can enhance their perception and communication skills while strengthening your bond. Just remember to use moderation and sensitivity when applying this technique, and always prioritize your dog’s well-being.


In conclusion, understanding what colors dogs can see best is crucial for pet owners who want to provide the best possible care for their furry friends. By knowing which colors are most visible to dogs, you can choose toys, collars, and other products that are more likely to grab their attention and engage them in play.

It’s important to remember that dogs don’t see the world in the same way that we do. While humans have three types of cones in their eyes that allow us to see a wide range of colors, dogs only have two types of cones, limiting their color perception. However, this doesn’t mean that dogs see the world in black and white. They can still see some colors, just not as many as we can.

As we’ve discussed, dogs see yellow and blue colors best, with violet and gray being the next most visible colors. On the other hand, they struggle to see green, red, and orange, which can appear muddy or dull to them.

To get your dog’s attention, it’s best to use colors that offer high contrast, brightness, and saturation. For example, a bright yellow tennis ball against a green lawn would be easier for a dog to spot than a red ball that blends in with the grass.

Overall, while dogs may not see the world in the same way as humans, understanding their visual capabilities can help pet owners provide better care and interaction with their beloved pets. So, when shopping for toys or accessories for your dog, consider the colors that will be most visible to them to make playtime even more fun and engaging.
From this comprehensive guide, we can conclude that dogs see color differently from humans, but they are not completely colorblind. They can perceive some colors such as yellow, blue, and violet, but struggle with others like red and green. Understanding how dogs see color is important in training and getting their attention, as high contrast, brightness, and saturation can help them differentiate between objects and commands. Knowing which colors to use and avoid can also improve their quality of life and prevent accidents. As dog owners and lovers, it’s essential to empathize with our furry friends and adapt our communication to their unique visual perception. By doing so, we can strengthen the bond between humans and dogs and provide them with a happier and safer environment.
