Color Deficiencies

About 8% of men and 0.04% of women suffer from some form of color deficiency. So, if your Web site primarily attracts a male audience, it is very important that you design a Web site to ensure usability for the 8% of men that are color deficient.

The most common form of color deficiency is red-green, which is the inability to distinguish between red and green. The second most common form is blue-yellow. So avoid using color combinations that could cause problems for color deficient users.

The most severe form of color blindness is achromatopsia - the inability to see any color - and is often associated with other problems such as amblyopia (lazy eye), nystagmus, photosensitivity, and extremely poor vision.
