jquery本身不支持变色，Jquery Color.js弥补了这缺陷并为animate动画赋予变色效果
例子：
<!DOCTYPE html>
<html>
<head>
<style>
div {
background-color: #bada55;
width: 100px;
border: 1px solid green;
}
</style>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="jquery.color.min.js"></script>
</head>
<body>
<button id="go">Simple</button>
<button id="sat">Desaturate</button>
<div id="block">Hello!</div>
<script>
jQuery("#go").click(function(){
jQuery("#block").animate({
backgroundColor: "#abcdef"
}, 1500 );
});
jQuery("#sat").click(function(){
jQuery("#block").animate({
backgroundColor: jQuery.Color({ saturation: 0 })
}, 1500 );
});
</script>
</body>
</html>
支持的其他属性如下
backgroundColor, borderBottomColor, borderLeftColor, borderRightColor, borderTopColor, color, columnRuleColor, outlineColor, textDecorationColor, textEmphasisColor
