It is easy, if you have a span next to it:

*, *:before, *:after {
  box-sizing: border-box;
}
body {
  background-color: #eee;
  font-size: 23px;
  padding: 50px;
  font-family: 'Ubuntu Condensed', sans-serif;
}
.seen {
  margin: 20px;
  float: left;
  padding: 20px 20px 20px 20px;
  border: 1px solid #ccc;
  background-color: #fff;
  position: relative;
  text-decoration: none;
}
.seen {
  color: green;
}
.seen:visited {
  color: red;
}
.seen + span {
  color: #fff;
  margin-left: 20px;
}
.seen:visited + span {
  color: #ccc;
  margin-left: 20px;
}

This doesn't work in Chrome, but works in Chromium!
