Understanding Dog Vision

The video debunks the myth that dogs can only see in black and white, explaining that while dogs are colorblind from a human perspective, they can still perceive colors. Humans have three types of cones in their eyes for detecting blue, green, and red light, whereas dogs have two types, allowing them to see blue and yellow. Dogs cannot see red but can distinguish between various shades of yellow, blue, and gray. Experiments show that dogs can differentiate between different shades, proving they do not see in grayscale. The video concludes with a call to action for viewers to engage with SciShow.
