Are Dogs Color Blind? The Truth About Color Blindness In Dogs

There was a time when dogs were thought to be completely color blind, unable to see anything but shades of grey. While their range is limited compared to the spectrum we see, our pups do perceive color.
Basically, dogs are able to distinguish between yellows, blues, and violets; but cannot distinguish between reds, greens, and oranges.
These colors appear somewhere on their yellow to blue spectrum.
A new study conducted by Italian researchers at the University of Bari's Department of Veterinary Medicine sought to put this red-green color blindness - a condition known as deuteranopia - to the test.
The researchers used a variation of the Ishihara Color Vision Test. In humans, the test involves a series of colored circles with numbers in them. If a person can't see a red number in a green circle, he or she has deuteranopia.
In order to customize the test for their purposes, researchers placed a series of silhouettes showing a running cat inside the colored circles instead of numbers.
