I think that the difference between human eyes & dog eyes is that all dogs are color blind but not all humans are color blind. We can see in color as dogs cannot.Yes this is the maindifference but I would like two point out that through dogs are color blind that they do indeedsee in color but they are missing a type of cone that humans have and they have way less. Dogs have a lot more rods then humans.
no color blind people are mainly red-green colorblind or less commonly blue-yellow colorblind
Like left-handedness, color blinded only affects less than 10% of the population. Color-blindness is also classified as a deficiency, although a color blind person can have advantages over someone who is not.
actually indians have any eye color like my friend has blue eyes
Yes! Dog's have two cones permitting them to see blue and yellow, where-as humans have three, blue, yellow, and red. This is where the misconception of being 'color blind' comes in, as technically they are color blind to the color red, but that doesn't mean they can't see any color at all! However, dog's eye sight isn't very good, as they use it less then any of their other senses, and their often large muzzles create large blind spots. They are good at seeing movement, and hardly anything else. For the most part, they rely on their nose to act as their 'eyes'.
Only about 10% of Americans are colorblind, most of which are male.
While it is uncommon to have black hair and green eyes together, it is entirely possible. Eye color is determined by genetics while hair color is influenced by a different set of genetic traits, so the combination of black hair and green eyes is just a less common genetic occurrence.
About ten million different colors on average. Of course, those that are color blind can see much less.
It depends. If you want a dramatic change in color, then no. You would have to either wear colored contacts or get Coloriris implants, but you can naturally change your eye color just "slightly". For instance, if you have grayish-green eyes, there are ways to make your eyes look more or less a certain color. Wear something that complements one of your many eye colors and your eyes will appear as that one color.
The normal color of human eyes ranges from brown to blue, with variations such as green, hazel, and gray also common. Eye color is determined by the amount and distribution of melanin in the iris, with brown eyes having more melanin and blue eyes having less.

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.
