Can you guess which three colors dogs can actually see when looking at the world?
Red, Blue and Green?
Black, Blue and White?
Yellow, Blue and Gray?
Green, Orange and Purple?
White, Black and Gray?
While we can't ask dogs to read an eye chart or pick out colors, behavioral tests suggest that dogs see in shades of yellow and blue and lack the ability to see the range of colors from green to red. In other words, dogs see the colors of the world as basically yellow, blue, and gray.
