How does my choice and use of color affect the accessibility of my website?
As people create websites or electronic documents, they should consider whether their use of color will prevent some users from accessing their content. Any information that is communicated using color should also be communicated using some means other than color. For example, if color is used to differentiate link text from other text on a page, users who are unable to perceive color differences will be unable to spot the links. A solution in this example would be to underline the link text or provide some other cue other than color alone.
