Jquery淡出RollOut

Question

下面的Jquery脚本有两种背景颜色，分别设置为在翻转和展开时启动。有没有办法让翻转颜色在推出时消失，而不是淡化另一种颜色？

提前感谢您的帮助。

Jquery的

jQuery(document).ready(function($){

    //Set the anchor link opacity to 0 and begin hover function
    $("#menu-sample-menu li").hover(function () {

         $(this).stop().animate({backgroundColor:'#3333CC'}, 300);

        //On mouse-off
    }, function () {

     $(this).stop().animate({backgroundColor:'#000000'}, 200);

    });
});

HTML

<nav id="access">
    <ul id="menu-sample-menu" class="menu">
        <li id="menu-item-198" class="menu-item menu-item-type-taxonomy menu-item-object-category menu-item-198"><a href="http://www.threecell.com/demo/category/health-care-professional/">Health Care Professional</a>
