my li.current_page_item a text isn’t showing

the current page background color seems to work, but the text on the hyperlink will not, even though it is set to “black”. however, when i hover over the hyperlink, the black text shows. i provided my code below.

here is my css:

#menu {width:950px; background:url(images/gray.jpg) repeat-x; margin-top:-20px;
font:normal 14px arial, sans-serif; letter-spacing:1px; height:30px}
#menu ul {list-style-type:none; margin:0 auto; padding:0; background:none;}
#menu li {float:left; padding:7px 0px;}
#menu li a {padding:7px 20px; color:white;}
#menu li a:hover {background:white; text-decoration:none; color:black; }
#menu li.current_page_item {background:white; color:black}
#menu li.current_page_item a {color:black;}
#menu li.current_page_item a:link {color:black;}
#menu li.current_page_item a:active {color:black;}

here is the php in header.php:
<div id=”menu”>
<?php wp_list_pages(‘sort_column=menu_order&depth=1&title_li=’); ?>
</div><!– end menu –>
