text colour in "comments"

Hi, maybe someone can advise me...
I like to have dark backgrounds in my guestbook and have set the text to white (#FFFFFF); however, I do not know how to change the "comments" text (right under each message) from the default black which is very hard to read against a dark background. Could anyone help please?
The guestbook in question is here:

You can make the change in com.php

At about line 4 you should see

<font size="1" face="Verdana, Arial, Helvetica, sans-serif">

Add your colour attribute to that tag. If you don't like the size of the text you can change that as well.
