I don't have a clue? But you can make the text + line the same color, there are several ways:
<s style="color:red;">MY RED TEKST WITH RED LINE</s>
or
<font style="TEXT-DECORATION: line-through; color:red;" >MY RED TEKST WITH RED LINE</font>
or
<s><font color="red">MY TEKST WITH RED LINE</font></s>
I think I didn't realy help you with this contribution, but I hope it helps a bit,
