well the easiest thing you could do is css puesdo script.

.alt1:hover {
background-color: #EBEFF2;
}

something like that. But this would be used for anything with the class alt1.

the second thing you could do is edit the threadbit template

find

<td class="alt1" id="td_threadtitle_$thread[realthreadid]" title="$thread[preview]">

change to <td class="alt1" id="td_threadtitle_$thread[realthreadid]" title="$thread[preview]" OnMouseOver="this.style.background='white';" onMouseOut="this.style.background='red url(images/alt1.gif) repeat';">

and change the colors that you want to whatever you want also the background image to the original alt or color.
