Can I set different appearance for admin's comments?

[doctor_paul]

How is it possible to make the administrator's comments style differently to the other users?

For example a separate background colour so taht everyone can immediately see that the admin has posted a comment? Is this possible?

I imagine its something to do with CSS but I wouldn't know how to do it.

Thanks

I found info at russian forum how to change color of usernames. Maybe enough for me. 

#comments .usertype-super-administrator .comment-author {color: red !important;}
#comments .usertype-registered .comment-author {color: green !important;}
#comments .usertype-guest .comment-author {color: blue !important;}
