Menu highlight problem

Hi,

I would like a highlighted menu so I’ve added the following css and offcourse the php-code.

#header #header-menu ul li a:hover {
		color: #000000;
		background: url("images/header_menu_hover.gif") no-repeat;
	        }

		/* Header - Menu - Active */

		#current a:link, #current a:visited {
                color: #000000;
                background: url("images/header_menu_hover.gif") no-repeat;
                }

The problem is that with hover the text color becomes black, as desired. With active the text is white and here I also want the text black. The background is shown correct.

Anybody suggestions? Would be very welcome.
