By default, all browsers display unvisited links — a state when users haven't clicked the link yet — underlined and blue. You can apply your own styling using the CSS attribute style and a:link value, for example:

style

a:link {

color: green;

}

Keep in mind that interactive elements like links should remain recognizable and look clickable. While blue is still a safe bet, other colors also work well, as long as the links stand out clearly from the body text.
