Humans can see three main colors – red, green, and blue. This is called being "trichromatic." It means we can see many shades and combinations. We enjoy full-color vision.

Dogs are "dichromatic." They can only see two main colors – blue and yellow. They cannot see red or green like we do. Their color vision is more limited.
