Como alterar cor do link que aparece nas widgets sem alterar os demais links?

Veja se são estes os códigos:

<div id="secondary">

<div id="sidebar-1" class="sidebar">

	<ul class="xoxo">
	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(1) ) : ?><!--sidebar-1 widgets start-->

		<li id="recent-posts" class="widget">
			<h2><?php _e('Recent Posts'); ?></h2>
			<ul>
				<?php wp_get_archives('type=postbypost&limit=10'); ?>
			</ul>
		</li>

		<li id="categories" class="widget">
			<h2><?php _e('Categories'); ?></h2>
			<ul>
				<?php wp_list_categories('title_li='); ?>
			</ul>
		</li>
	<?php endif; ?><!--sidebar-1 widgets end-->
	</ul>
</div><!--#sidebar-1-->

<div id="sidebar-2" class="sidebar">

	<div id="pp-search">
			<?php include(TEMPLATEPATH . '/searchform.php'); ?>
	</div>

	<ul class="xoxo">
	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(2) ) : ?><!--sidebar-2 widgets start-->

		<li id="calendar" class="widget">
			<h2><?php _e('Calendar'); ?></h2>
			<div id="calendar_wrap">
				<?php get_calendar(); ?>
			</div>
		</li>

		<li id="pages" class="widget">
			<h2><?php _e('Pages'); ?></h2>
			<ul>
			<?php wp_list_pages('title_li='); ?>
			</ul>
		</li>		

		<?php wp_list_bookmarks('class=widget'); ?>
		<li id="meta" class="widget">
			<h2><?php _e('Meta'); ?></h2>
			<ul>
			<?php wp_register(); ?>
			<li><?php wp_loginout(); ?></li>
			<?php wp_meta(); ?>
			</ul>
		</li>
	<?php endif; ?><!--sidebar-2 widgets end-->
