PHP background rotate

Hi,

Ik ben voor Patrick bezig om zijn Wordpress site goed te krijgen. Nu wil ik bij de comment functie dat je bijvoorbeeld dit krijgt:

wit
zwart
wit
zwart

Maar ik heb geen idee hoe ik dat hier voor elkaar ga krijgen. Wie zou mij kunnen helpen?

Alvast bedankt!

Code

function twentyten_comment( $comment, $args, $depth ) {
    $GLOBALS[comment] = $comment;
    $comments_count = wp_count_comments(get_the_ID());
    
    switch ( $comment->comment_type ) :
        case  :
    ?>
    <div id="comment-[COLOR= #0000BB]<?php[/COLOR] comment_ID[COLOR= #007700]();[/COLOR] ?>">

Ik weet niet precies hoe je het in de functie krijgt, maar:
