There’s a generational belief we all have heard regarding dog’s vision that they can’t see the colors of this beautiful world. Instead, they are bound to see it in the black and white spectrum. It has made many owners wonder at some point, Are dogs color blind? To know the facts behind this folk fiction, we will delve into different perspectives regarding dogs’ vision and how they see colors.
Science Behind Canine Vision: Are Dogs Color Blind?
This myth regarding a dog’s vision has come from the reactions that dogs exhibit to colors. It is not the same way as humans do. There was a vague notion about their vision that they could see in black and white. That later changed into color blindness. Perhaps, scientific research has disapproved of these fallacies stating: that dogs can see colors but not all, and their frequency range is different from human eyes.
Additionally, it is due to structural differences in the dog’s eyes compared to humans, particularly in terms of cones in their eyes. These cones are the photoreceptors, allowing eyes to detect colors. In humans, there are three types of cones, making them see a wide range of colors easily. Meanwhile, dogs’ eyes have only two types of cones in them. Typically recalled as dichromatic vision. It hinders them from seeing all shades accurately. Similar to human vision, experiencing red-green color blindness. Science has declared this structural difference of eyes and vision in dogs as Canine Vision. That means they can see colors and aren’t blind.
Understanding Dog Color Spectrum: Can Dogs See Color?
Dogs can see but due to their dichromatic vision, they possess only two types of cones ( yellow and blue) that confine their vision. Contrarily, humans have trichromatic structures of eyes meaning they have three cones (red, blue, and green). Allowing people to see all colors freely.
Therefore, the dog color spectrum is limited because they lack color receptors of red and green. For example, human eyes can detect all colors of the rainbow while dog color vision allows them to see it as shades of gray and yellow. Knowing this difference in color vision will help dog owners in selecting tools and toys for their pups. Furthermore, there is a unique vision of dogs that they can see well in the dark compared to human night vision.

How Do Dogs See Color Compared To Humans?
As discussed earlier, the distinction in eye structure has set a different foundation of vision for both humans and dogs. Imagine a world without vibrant red and lush greens that the human eye cherishes with trichromatic vision. While a dog’s color vision is the same as a person with red-green color blindness, Who is unable to see the beauty of green grass or a vibrant sunset? Due to its unique retinal structure, dogs can see better at night and can sense fast-moving things quickly. This specific distinction is in their eyes relative to humans makes them see red as brown and green as hues of gray. This explains how dogs see color differently.
Why Do Dogs See the World Differently?
It might seem a little unfair to you as a dog owner that they can’t see the colors as humans. Thus, it has also bestowed them with a significant ability of strong night vision and a good sense of smell. That’s the reason behind the survival of many dogs. Tier dichromatic vision may restrict them to fewer colors but they can quickly sense a fast-moving thing and recognize anyone by smell. The ability to distinguish is not more crucial than their survival. This divergence of the color spectrum in them is due to a unique retinol structure. That makes them loveable and helps them to survive in this world.
Bottom Line
In the tapestry of nature, dogs have a unique place. There is a myth from years ago that dogs are colorblind. No, they are not. Science has studied all types of colorblindness and the structure of dogs’ eyes settle for none. They possess unique eye structures with canine vision. So the right answer to Can dogs see colors? Yes to some extent except the shades of red and green.
