javascript - jQuery each letter in div element, random colour from array on hover

Question

I'm trying to get each letter in a div element to change to a random colour from an array of colours. Then reset when the mouse moves off the div.

Here's what I've got so far. I think I'm pretty close, apart from the fact it doesn't actually work. This was built from a few different snippets on this site.

$(document).ready(function() {

    // COLOURS ARRAY
    var colours = Array("#ddd", "#333", "#999", "#bbb"), idx;

    $("DIV#header").hover(function(){

        $( $(this).text().split('')).each(function(index, character) {
            idx = Math.floor(Math.random() * colours.length);
            $(this).css("color", colours[idx]);
        });

    }, function() {
        $(this).css("color","#ddd");
    });

});

It doesn't produce any JS errors. The 2nd function of the hover seems to work but not the first. Any help would be gratefully received!

You can only add styles to elements, wrap each character in a <span> and style the span.

#header {color: #ddd}?

<div id="header">Some text here</div>?

$(document).ready(function() {

    // COLOURS ARRAY
    var colours = Array("#ddd", "#333", "#999", "#bbb"), idx;

    $("#header").hover(function(){
        var header = $(this); 
        var characters = header.text().split('');
        header.empty();  
        var content = '';
        for(var i = 0; i < characters.length; i++) {
            idx = Math.floor(Math.random() * colours.length);
            content += '<span style="color:'+colours[idx]+'">' + characters[i] + '</span>'; 
        }
        header.append(content);
    }, function() {
        $(this).find('span').contents().unwrap();
    });

});
