Use color changes to indicate to users when a link has been visited.


Link colors help users understand which parts of a website they have visited, and can increase users’ ability to find information. Use default text link colors such as blue for unvisited links, and purple for visited links. Ensure that all links sharing the same target (e.g., external websites) change colors as well.


Poor Example:

A poor design choice. Unvisited links are in green, whereas visited links are in blue - users expect blue to denote an unvisited link.


Good Example:

A good design choice - unvisited links are shown in blue, and visited links are shown in purple. Note the conventional use of colors for visited and unvisited links.
