[SOLVED] Styling navigation link color in center column - HELP!

I'm having a heck of a time trying to change the color of the next post/previous post and comment page navigation links in the center column.

I've tried two other solutions I found elsewhere in this forum to what sure sounded like exactly the same problem. Those solutions didn't indicate where to insert the code, so tried it in CSS inserts, in the style boxes for above and below the comments, in the navigation top, middle and bottom boxes, and in the center column style box - nothing works. This is so frustrating!

Here's what I've tried (copied and pasted directly from other forum posts marked "resolved"):

div.navigation-top a:link, div.navigation-top a:active, div.navigation-top a:visited, div.navigation-top a:hover {color: #ffffcc};

div.older a:link, div.older a:visited, div.older a:active {color: #FFFFcc;};

Here's a page with top previous past nav links which are only visible upon hover, since they currently match the background color:

Here's the same problem navigating to previous comment pages:

What am I doing wrong??
