New research has led scientists to believe that people may not see all the same colors when they look at the same things. It comes down to color perception. Although most of us would agree that red is the color of tomatoes, strawberries and stop signs, scientists now think that one person's red could be another person's blue.
Color blindness affects more than 3 million Americans each year. Men are more prone to this condition than women. Even though millions of Americans are affected by it, not many know what it actually is. This condition is also known as “specific color vision deficiency (CVD)”, because there are different types of blindness when it comes to seeing colors.
