JQuery only adding to children of odd even index
<p>I have the following JQuery:</p>

<pre><code>$(document).ready(function () {
    $('tr').hover(function () {            
        $(this).children().addClass("color2");
        $(this).children().removeClass("color1");
    });
});
</code></pre>

<p>But I only want it to add onto a <code>td</code> element which has an even index (including 0)</p>
