Advanced guestbook: change the color of comment's font

hello

I would like to change the comment's color
it still black in IE which is unreadable on a black background

No problems with Opera?!?

Where can i change that?

Thanks

open templates/ folder and find you default used style. if you use aq, open it ,edit the style.css file with any editer..

thanks for your help
but i diden't find any *.css file in template folder.
There are only *.php files.

Why with Opera browser the comments apear in white like all posts and in IE the comments are in black color? It is strange. The same HTML page is presented differently.
