JQuery Random background color, 2 div's

I want to create a jQuery script that will randomly select a color from a list of 10, and then apply it as a background color to a single div and the color of the h1 tag.

So far I have this, which makes a random color:

$(document).ready(function() { var hue = 'rgb(' + (Math.floor((256-199)*Math.random()) + 200) + ','
                 + (Math.floor((256-199)*Math.random()) + 200) + ','
                 + (Math.floor((256-199)*Math.random()) + 200) + ')';
$('#controls-wrapper').css("background-color", hue);
$('h1').css("color", hue);});

but how can I do it randomly from a list of 10 colors? I found this, but not sure how you apply this to the bg color div and h1 tag.

$("#controls-wrapper").each(function(){ 
var colors = ["#CCCCCC","#333333","#990099"]; 
var rand = Math.floor(Math.random()*colors.length); 
$(this).css("background-color", colors[rand]);});

I think you are trying to accomplish this:

Assuming you have an HTML page like this:

<html>
<body>
  <h1>Hello World!</h1>
  <div id="controls-wrapper>some text</div>
</body>

$(document).ready(function(){
  var colors = ["#CCCCCC","#333333","#990099"];                
  var rand = Math.floor(Math.random()*colors.length);           
  $('#controls-wrapper').css("background-color", colors[rand]);
  $('h1').css("color", colors[rand]);
});

After creating an array of colors, you will get a random number corresponding to the color index.

Now that you have a random index, you can use it to set the background or color of the text of the object.

, ,

rand = Math.floor(Math.random()*colors.length);

.

, , $('h1').css("color", colors[rand]);, H1 , , H1, $('h1.myclass').css("color", colors[rand]); $('#ID_for_my_H1').css("color", colors[rand]);

var randomLinks = $('a.random-color');
var original = randomLinks.css('color');
var colors = ["#CCCCCC","#333333","#990099", "#1295A6", "#FFFF99"]; 
randomLinks.hover(function() { //mouseover
    var col = Math.floor(Math.random()*colors.length);
    $(this).css('color',colors[col]);
    $(this).animate({
        'paddingLeft': '20px'
    }, 1000);
}, function() { //mouseout
    $(this).css('color',original);
    $(this).animate({
        'paddingLeft': '0'
    }, 500);
});

var array = ["orange", "blue", "black", "yellow", "green"];
var colorNumber = Math.round((Math.random() * (array.length - 1)));
$("body").css('background-color', array[colorNumber]);
