Some animals are color blind... Just some can see some certain colors, like a horse can see blue's and greens, deer can see yellows and greens..etc...
Dogs most definitely are not color blind. There are some differences in their vison from that of humans, but -- contrary to popular myth, their eyes contain both rods (cells that detect light and movement but not color) and cones (which detect color and need more light than rods do in order to activate).
Rods are groups of light sensors connected to one neuron. Cones, on the other hand, are one neuron per cone and, unlike rods, have a narrow range of wavelengths they'll respond to. Dogs' cones respond to, what in the human range of vision, would be yellow, and blue-indigo.
Most breeds of dogs also do not resolve images well at distance, with a focal range of about 20/70 (to a human's healthy vision of 20/20). This means, what you see at 75' is about what a dog sees at 20' (exceptions are Labrador Retrievers, who approach 20/20 -- which is why they're often used as guide dogs).
Dogs also have a wider angle of acceptance -- around 270 degrees (as opposed to a human's 180 degrees). This means they are more aware of events on the periphery of human sight of course, but as the acceptance angles of vision of the two eyes don't intersect as completely as humans, they don't get really good distance ranging except for a small angle of acceptance directly in front of them.
You can pretty easily test this if your dog likes retrieving. Get a bunch of identical balls in different colors, and watch for the surprisingly different reactions.
CLARIFICATION: TURTLES ARE NOT COLOR BLIND!
Source: Turtles, Tortoises and Terrapins: Survivors in Armor by Ronald Orenstein.
At least some turtles can see in the red-orange-yellow part of the spectrum...box turtles (for example) like to eat berries, and the color vision can help them spot the ripening fruit.
and bees.
Birds are not color blind because you can teach a parrot to recognize colors. This is also true in a peacock's colorful wings.
Good point! While dogs have only two types of cones (see above about cones and rods) that detect yellow and blue-indigo, and humans have 3 (Cyan, Magenta, Green or Red/Yellow/Blue), birds have four, with the ability to see into the ultraviolet as well.

Pure white, shorthaired cats with two blue eyes are often deaf (not blind!)
Pure white, Persian longhaired cats, are color blind.
One in four human males has a form of colorblindness, with differing levels of severity, or acuteness.
Deer are color blind. This is why hunters where blaze orange. It stands out for the hunters, but isn't noticeable for the hunted.
A little more..Because deer don't clearly contrast and react to International, Day-Glo(TM) or Safety Orange doesn't mean they're colorblind. It only means they're not able to clearly differeniate these particular frequencies from others. I'm inclinsed to guess that, when deer graze, the identification of food is partially color identification -- but that's a guess.In fact, very few if any animals perceive only in monochrome or gray-scale. Barring extreme neuro-trauma, humans never do. Even in cases where severe brain injuries plays a part, the most extreme case I've seen documented (Sax et al, "Anthropologist on Mars") was an artist who, after a severely neuro-traumatic event, could only see in gray-scale and in a very narrow frequency span in the yellow-orange region....

Can animals see ultraviolet color?
bees
Are all animals colourblind?
No, not all animals are color blind. Some see less color pigmentation than others, which as a general rule would be those animals with good night vision. People, which by definition are animals, are for the most part, not color blind.
Is there a color blind test for animals?
No, there is no color blind test for animals that you can do at home. There actually is no color blind test at all, only tests to check their vision if they can see at all.
Why do certain animals see colours differently from humans?
Different animals have different kinds of color vision. Some have very poor color vision and others have very good color vision. In fact some birds and bees have super color vision and see colors that humans don't see.
Do all animals have black and white vision?
No some animals can see in negative color. some dogs cant see hardly anything. others can see colors but are color blind meaning they see colors as different colors. for example some people can see red when they are really looking at green.
Can animal see colors?
Animals can see in color not every color but most of them.Answer:Science indicates that many animals see colours although the palate they see is more limited than ours. Birds and some reptiles obviously devote a fair amount of energy into being coloured to attract mates, birds and other animals are attracted to coloured fruits and flowers, dog's can be trained to fetch balls of specific colours, insects use colours to warn predators away (hornets and Monarch butterflies) - all of these actions would be useless if animals could not see colours.
Why animals see in black and white?
Some animals can see in full color like humans. Though some animals have cones in their retina (which are used to see color) that cant distinguish the colors other than the color black (when no light is reflected off the surface) and the color white (all light is reflected). All the other colors are just the amount of light that's absorbed and reflected, the darker colors would show up close to the color black.
Are there animals that can see more color then people?
I don't think that there is an animal that can see better than a human... But there are animals that can hear better, such as cats, dogs, deer, etc.
What animals can not see in color?
Most mammals, such as dogs and cats, are believed to be colorblind and see the world mainly in shades of gray. However, some research suggests that certain animals, like monkeys and apes, have the ability to see some colors.
Can a horse see color?
Animals, including humans, have "rods and cones" in the eye that allow them to see color. Horses have some, but not as many as humans, so it is believed that they see color, but pastels. These colors would be associated with food, water, and blood.
Do all animals see in black and white?
No, not all animals see in black and white. Some animals, like humans, see in color. Others, like dogs and cats, see in shades of gray and some colors. It depends on the animal's eyes and how they perceive light.
Why are dogs scared of red color?
No, dogs see in black and white, most animals(those that hunt at night) can't see colors.
