what color do dogs see best

Dogs can see some colors, but not as many as humans. They have dichromatic vision, meaning they have only two types of cones in their eyes that correspond with blue and yellow. This means that dogs can see blue, yellow, and some shades of gray. They cannot distinguish between red and green, which appear as shades of gray or brown to them. Dogs see the world in a less vibrant way than humans, but their world is not entirely black and white. According to research, a dogs color vision is most similar to that of a person who has red-green color blindness. Therefore, dogs can distinguish some colors, but not as many as humans. When it comes to toys, blue and yellow toys are more visible to dogs than red or green ones, which appear as shades of gray or brown.
