Sitemap Link Colors

I changed the link colors in style.css to white because my menu items (under categories, information, etc.) are on a dark background. However, this change also m made ALL page links (i.e. my sitemap) white as well, and they cannot be seen since the page is a white background in that area. What's the best way to recolor the sitemap links -- create a new entry under styles.css and change the div for the sitemap? Are there any other pages like this were issues might come up?
