No, dogs are not color blind but they may not perceive colors in the same way as humans do. There are 2 types of photoreceptors called rods and cones that are present in the retina. This is where the animal’s ability to process color occurs. Rods help see objects in dim lighting conditions, while cones function in bright light. Cones play a primary role in how color is perceived. The human eye has cone-rich areas that enhances the ability to see things, including color. Dogs have fewer cones than humans thus their ability to perceive at certain distances won’t be as clear compared to humans. On the other hand, dogs have more rods than humans, giving them an advantage in dim lighting conditions. Humans are able to perceive the full color spectrum because we have 3 cone photoreceptors for red, blue, and green. Dogs only have 2 of these photoreceptors. They lack the green cone, thus they tend to confuse red and green colors, and are often perceived as grayish shade. Because of these, the colors that dogs see are mostly blue and yellow variations. They then rely on their other sense organs to identify or distinguish objects that appear similar in color.
