CSS - a:visited:hover?

Question

How can I apply a font color only to hyperlinks which have already been visited and are being hover by the mouse?

Essentially, wha

Answer 1

FWIW, I was unable to style just color on a:visited:hover (Chrome/FF) without declaring a background for :link:hover (anything other than none or inherit seems to work, I used rgba() for alpha sake).

For this to work in Chrome/FF:

a:visited:hover {
    color: #f00;
}

... (something like) this must be present:

a:link:hover {
    background-color: rgba(255, 255, 255, 0);
}
