Colorblindness is a common condition, especially among white males. Studies vary on just how many white males do suffer from colorblindness although it is safe to say that somewhere between 12 percent and 20 percent cannot differentiate between certain colors.

While it is more common among white males, a small fraction of females are considered to be colorblind as well.

Being colorblind does not necessarily mean that a person only has the ability to see black, white and shades of grey. While that is an actual and unfortunate level of colorblindness, it is rare.

The majority of people who suffer from colorblindness are unable to distinguish green, red or blue colors. These are milder forms of colorblindness and can also be referred to as color deficiencies.

Since many forms of colorblindness can be so mild, it is not irregular for a person to go through his or her entire adolescence without even noticing that what they were seeing in the crayon box, on the television screen, on clothes and in pictures was an incorrect perception of color!.

Unfortunately many people learn of their condition at the worse possible time - during the job application process. Many industries require potential employees to take the Ishihara Color Blindness Test before a decision to hire is made.

These industries include law enforcement, engineering, railroad operation and aviation. Doctors today are still using the Ishihara Color Blindness Test that consists of 38 circles that are patterned with dots. In the center of each circle, the color of the dots are shaded various colors to display a hidden number. If the person being tested fails to find the numbers in the circles then he or she would be considered as someone with a form of colorblindness.
