                     The page contains colors, so make sure the information
                     conveyed with the page does not rely on those colors.
                     
                  </p>

                     Make sure the page can be understood and navigated even if
                     users do not have the ability to identify specific colors
                     or differentiate between colors.

                     Here are easy ways to test the page:
                     
                  </p>

                     <li>
                        View the page on a black and white screen and go through
                        each of its elements
                        
                     </li>

                        Print the page on a black and white printer

                     There are many situations where a person cannot see colors.
                     They include:
                     
                  </p>

                     <li>
                        Bad choice of background or foreground colors on the page
                        
                     </li>

                     Colors on a page should be used only as decorative or
                     graphic-enhancing devices. They should not be used to
                     convey information.
