setAttribute("color","red");和style.color="red"效果为什么不一样？

//创建链接
function createa(url,text)
{
var newnode=document.createElement("a");
newnode.innerHTML=text;
newnode.href=url;
//newnode.style.color="red"
newnode.setAttribute("color","red"); //不能实现文字红色效果
main.appendChild(newnode)
}
// 调用函数创建链接
createa("http://www.imooc.com/","慕课网");
