Color Blindness
Around the world , tens of millions of people are color blind. Usually, "color blindness" doesn't mean someone can't see color. Instead, it means some of the colors they see look different.
There are different kinds of color blindness. Red-green color blindness is the most common type. For the most extreme cases, red and green look the same.
The second kind , blue-yellow color blindness, is much less common. It makes blue and yellow appear similar.
Finally, people who can't see color at all are very rare. To them, the world look black and white.
Some people have mild cases of color blindness. Others have complete color blindness. For all cases, color blindness is rarely a serious problem.
