This policy setting prevents users from changing the color of Web page links that they have not yet clicked. Appropriate color choices can make links easier to see for some users, especially those who use high-contrast color schemes.

If you enable this policy setting, a user cannot configure the color for links not yet clicked in Internet Explorer. You must specify the link color (for example: 192,192,192).

If you disable or do not configure this policy setting, users can choose the color for links not yet clicked.
