If you have any questions or concerns, you should always visit or call your veterinarian – they are your best resource to ensure the health and well-being of your pets. Scientists did some research about a hundred years ago that led them to believe that dogs were color blind. When a human was thought to be color blind, these cone-shaped cells were often found to be lacking. Scientists from the American University have conducted new research that has determined, once and for all, that dogs do indeed perceive color. Like the earlier research says, humans do have three cone-shaped cells that perceive color.
Where they differ from the earlier research is in the presence of these cells in the retinas of dogs.

Take black and white pictures of an assortment of colored construction paper to determine which colorsappear to have similar and dissimilar degrees of brightness and shade.2. Modern science has answered this age-old question: Dogs can see color, but not in the same way that we do.
Rods tell us how bright or dim something is (black or white) and cones help us identify color. There has been a long-standing myth surrounding the colors that a dog is capable of seeing.
Cover two jars with different colored construction paper that share a similar shade when photographedwith black and white film. The dog needs color vision to distinguishbetween the two jars, since with complete color blindnessthe two colors would appear to be the sameshade.5.
Rods process visual information in dim light and are sensitive motion detectors, while cones handle color and detail.

The palette of colors they can see is limited in comparison to ours; it is also less vibrant.
While they can see blue, they can’t distinguish shades, especially as the color blue gets darker. Cover the third jar with another color whose photograph shade is distinctlydifferent from the other two jars. Even though yellow andviolet appear to be similar shades in black and white photos, the dogswere able to choose the correct yellow jar 72% of the trials.This data supports our hypothesis,that dogs can see some shades of color.
