Handicapped Accessible Web Design

Are you losing customers who really want to buy from you? They may get to your site, add items to their shopping cart and at the last stage of checking out, they leave. This could be due to price, changing their mind, or something most people don't think about until it hits their bottom line - maybe they couldn't buy from you! If there isn't significant contrast, a consistent text based navigation, alternative content as necessary and so on, your color blind or blind visitors will be lost as Amazon.com and Microsoft found out in this article in support of handicap accessible web design.

Remember, half the human population is male, and 7-10% of all men are color blind to some degree, while .4% of women are colorblind (source). You don't want to lose 10 of every hundred visitors just because they couldn't see your information.
