What animals are color blind?

There are several animals that are color blind. Some pets like dogs and cats are color blind. Dogs are considered to be color blind because they can't see certain colors. These colors include red, orange and green. Dogs can tell the difference between those colors, but they appear more yellow or blue. The only colors a dog can see are yellow, blue and violet. Cats can distinguish between blues and greens but can't see shades of red. For birds, only the nocturnal birds, such as owls, are the only type of birds that are color blind. Also, scientists have discovered that whales and seals are missing cones in the eye. This means these animals are color blind.

Many animals are considered to be color blind. Animals and humans have rods and cones in their eyes that enable them to see color. The ability of an animal to see color depends on the color receptors in the retina of the eye. Some animals have less cones or more rods. This leads certain animals to see better at night, and see color differently. Color blindness affects animals from birds to pets to sea animals. Dogs are considered to be color blind because they can't see certain colors. These colors include red, orange and green. Nocturnal birds, such as owls, are the only type of birds that are color blind. They have a reflector in the back of the retina that reflects light.
