What color is hardest for dogs to see?

Have you ever wondered what color dogs struggle to perceive? It's an intriguing question that delves into the unique visual capabilities of our canine companions. Given their keen sense of smell and hearing, one might assume dogs have superior vision as well. However, the reality is quite different. Dogs, like humans, have cone cells in their eyes that detect color. But unlike us, they have fewer types of cones, limiting their ability to distinguish certain hues. So, which color poses the greatest challenge for dogs? Is it the vibrant reds or the serene blues? Or perhaps it's a hue that we don't even consider significant in our own visual experience? Let's explore this fascinating aspect of canine vision and find out which color truly poses the greatest difficulty for dogs to see.
