Here's how to make your own comments background color different from the rest of the commenter's without using plugin.
First Step
Open your style.css or whatever the name of your css and add the following code
.authcomment { /*Use different color to match your theme*/ background-color: #B3FFCC !important; }
Step Two
Open your comments.php and look for the line similar to this code since almost of the theme are derived from "Kubrick theme" which is the default theme of wordpress.
<li class="$oddcomment;" id="comment-<?php comment_ID() ?>">
And replace it with the following code
<li class="<?php /* Only use the .authcomment class from style.css + if the user_id is 1 (admin) */ if (1 == $comment->user_id) $oddcomment = "authcomment"; echo $oddcomment; ?>" id="comment-<?php comment_ID() ?>">
You are done! See my sample comment below.

@MP3 of course there’s a better way, you can use existing comment highlighter plugins. This tutorial show only how you can do it without plugins, and I think the simplier the better.
I enjoyed reading the How to highlight author comments in WordPress post, although I did not think it was entirely the best approach … there are alternatives which would provide more positive results ..
