The forumid is used as an id for each row, ie. forum id 2 has an id of forum2. So, just write some CSS for it like:

#forum1 .forumrow, #forum3 .forumrow {background-color: red;}

Do similar for forumid2 and forumid4.

Yes, I understand this, but I want to write a plugin or insert php to additional.css. When create one makes the box without having to manually edit.

You can't use php in css.

Have a look at this: http://www.ich-lerne-css.de/track.php?l=www.w3.org/Style/Examples/007/evenodd.html
