For an entire page? I suggest using CSS.
In your HTML page between <head> and </head> insert the following:
Code:
<style
type="text/css">
body a:link, body a:active, body a:visited {
color: maroon;
text-decoration: none;
}
body a:hover {
color: red;
text-decoration: underline;
}
</style>
The above has maroon-coloured links. When you hover the links they will be underlined and turn red. Change the colours and underlines as you need.
