You may have heard that a bull never literally "sees red" when the bullfighter waves a cape in his face. It's the movement of the cape that provokes. Animals, after all, are colorblind. Hold on, not so fast. Birds, for instance, have a marked ability to distinguish colors. They need it to spot food, such as berries, on the ground. On the other hand, most creatures of the night — including the ubiquitous house cat — have little sense of color. But they're awfully good at picking up movement.So the next time someone tells you that all animals are color blind, tell them that it's not such a black and white proposition.
