  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" type="text/javascript"></script>
            <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js" type="text/javascript"></script>
    <script src="js/evol.colorpicker.js" type="text/javascript"></script>
    <link href="css/evol.colorpicker.css" rel="stylesheet" type="text/css" />

<script>
        $(document).ready(function () {
            $('#txtcolor').colorpicker({
                initialHistory: ['#ff0000', '#000000', 'red']
            })
                        .on('change.color', function (evt, color) {
                            $('#body').css('background-color', color);
                        })
                        .on('mouseover.color', function (evt, color) {
                            if (color) {
                                $('#body').css('background-color', color);
                            }
                        });
        });
</script>

Complete HTML markup of webform:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<link id="jquiCSS" rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/themes/ui-lightness/jquery-ui.css" type="text/css" media="all">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" type="text/javascript"></script>
            <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js" type="text/javascript"></script>
    <script src="js/evol.colorpicker.js" type="text/javascript"></script>
    <link href="css/evol.colorpicker.css" rel="stylesheet" type="text/css" />
</head>
<body id="body" runat="server">
    <form id="form1" runat="server">
    <div>  
            <asp:TextBox ID="txtcolor" runat="server"></asp:TextBox><asp:Button ID="Button1" runat="server" Text="Change Color" />

    </div>
    </form>
    <script>
        $(document).ready(function () {
            $('#txtcolor').colorpicker({
                initialHistory: ['#ff0000', '#000000', 'red']
            })
                        .on('change.color', function (evt, color) {
                            $('#body').css('background-color', color);
                        })
                        .on('mouseover.color', function (evt, color) {
                            if (color) {
                                $('#body').css('background-color', color);
                            }
                        });
        });
</script>
</body>
</html>

protected void Button1_Click(object sender, EventArgs e)
    {
        body.Attributes["bgcolor"] = txtcolor.Text;
    }
