OK, so we know cats can see in color. Now comes new research indicating that dogs can see in color, too.
Three scientists at the University of California at Santa Barbara adopted the traditional strategy of trying to tempt the dogs with food. The menu, frankly, could have stood some improvement: would YOU cooperate with people whose idea of a reward was a cheese-and-beef-flavored pellet? Nonetheless, the researchers found three mutts who were sufficiently desperate to play along. They showed the dogs three screens lit up from behind with colored lights--two of one color, the third of a different color. The mutts got the pellet if they poked the odd-colored screen with their noses.
The dogs had no difficulty distinguishing colors at the opposite ends of the visible spectrum, such as red and blue, and they proved to be demons with blues in general, quickly learning to differentiate blue from violet. But they bombed at other colors, confusing greenish-yellow, orange, and red.
The researchers concluded that dogs suffer from a type of colorblindness that in humans is called deuteranopia. Normal humans have three types of color receptors for red, green, and blue. Deuteranopes lack the green receptor, and thus (apparently) can't tell a lemon from a lime--or, for that matter, a red traffic light from a green one. One more reason to put your foot down next time the pooch says he wants to drive.

They're not color blind to black and white.. but to red and green which is a symptom alot of men in the U.S. have.. more than women anyways, so they can mainly see blue and yellow and stuff like that..

They see washed out colors, like a picture tube about ready to go out. They can not see red and green at all

Most animals are colorblind, and most animals are colorblind so they can HUNT UPRIGHTS BETTER AT NIGHT
