Dogs can only see things in three colors, namely blue, yellow and gray. Every other color is rendered in your dog’s eyes as a shade of one of these three colors.
What Does The World Look Like To A Dog?
The ability to see color depends on certain photoreceptor cells in the retina known as cones. The human eye normally has three kinds of cones – blue, green, and red cones. In contrast, a dog’s eye has only two kinds of cones – blue and yellow.
Due to the lack of red and green cones, dogs cannot distinguish reddish or greenish shades of color. Dogs see the same way as someone who has red-green color blindness. This means that everything you dog sees is either bluish, yellowish, white, or gray.
For instance, if you throw a red ball on a green lawn, you can easily see the ball because of the contrasting colors, but your dog will have a harder time seeing the ball because both the ball and the lawn have a yellowish color in your dog’s eyes. This limited perception of color in dogs is referred to as dichromatic vision.
What Color Is The Easiest For a Dog To See?
Due to their dichromatic vision, blue is the most dominant color in a dog’s eyes and the easiest for them to see. Dogs will also clearly see the color yellow.
While dogs will distinguish colors that are close to blue and yellow, they perceive all other colors as shades of brown, gray, or plain white.
Can Dogs See Green?
Since dogs don’t have green cones, they don’t have the ability to perceive the color green. However, this does not mean that your canine buddy will not see a green object.
They will visually detect the object, but instead of seeing its green colors, they will perceive the object as having a yellowish shade.
What Does Pink Look Like To Dogs?
The color pink is a result of diluting the color red, and since dogs don’t have the cones that perceive the color red, they cannot see pink. Instead, your dog will see pink as a shade of gray.
