The belief that dogs are colorblind, especially that they can only see in black and white, is a common misconception that has been for many years. This misunderstanding likely early scientific studies and the way the information was subsequently communicated to the public. Early studies on canine vision suggested that dogs could not perceive colors in the same way humans do. This was because dogs, unlike humans, have fewer cone cells in their eyes. Cone cells are responsible for color. Humans typically have three types of cone cells, allowing them to see a spectrum of colors (trichromatic vision). Initial research suggested that dogs might lack this complexity in their visual system, leading to the conclusion that they could only perceive the world in of gray. Modern research, however, has shown that dogs do see colors, but their color vision is limited compared to humans.
