What Colors Can Your Dog See?



I was amazed to learn that Luke sees my favorite color, blue-green, as white!
That's my dog, Luke, up there and when he was a puppy we had a definite sense that he could understand every word we said.  A few of his key words are "walk", "play", "treats", and "bye-bye".  We learned early in his puppy hood to spell those key words instead of saying them out loud.  Now, I swear the little stinker can spell!

So, we got to wondering what else Luke Skywalker Sawaya could do.  Sure he has a catchy and befitting name due to his dark and light sides, but what abilities lie within those moniker-inspiring eyes.   I had read many times before that dogs could not see in color, only achromatically meaning black, white, and gray.   Knowing Luke, I didn't believe it and set out to find more information.

What I found was a study in which Dana K. Vaughan, Ph.D., Dept. of biology, University of Wisconsin, Oshkosh vounteered her two Italian Greyhounds named Flip and Gypsy. "Source" below is a link to her paper entitled "How Dogs See Color".  As a dog lover and total color geek, I found every word fascinating.

The results from the study tells us that dogs do see some colors: violet, indigo, blue, yellow and red.  They are especially adept at differentiating between shades of violet, indigo, and blue.  Who knew!!  "The colors Green, Yellow, and Orange all look alike to dogs; but look different from Red and different from various Blues and Purples."

"How Dogs See Color" advises us that in order "to maximize an object's visibility to a dog, we should strive to combine (1) moderate motion (when feasible); (2) maximal contrast (a dark and white pattern unlike that of the background scene); and (3) stand-out color (one that is identifiable by dogs and does not occur very often in the background scene).  The best of all possible worlds for most background scenes would be boldly-patterned Bright Purple and White objects."

    The dogsight info is sooo interesting. I had always just assumed the black and white thing. Maybe I can do some experiments with my pup. But I'm not sure if we should teach him about colors - he's already too smart for his own good.
    Luke is a cutie. Looks smart, too.
