According to Psychology Today, dogs do see in color just less colors than humans. Dogs tend to see hues of color that are not as rich as humans. Even though most dog toys are red or bright orange, dogs are likely to see these colors as brown or even black and may be difficult to distinguish on a lawn that appears as the same color to dogs. The colors that dogs can see are yellow, blue, brown, black and gray. They see the colors green, yellow and orange as yellowish, and they see violet and blue as blue. While blue-green is seen as a gray or brown.
