Google Charts - Change individual bar color

Question

With Google Charts bar graph, is it possible to to change the color of one bar. For example I'd like to make the 2006 data red (other bars are blue).

 function drawVisualization() {
            // Create and populate the data table.
            var data = new google.visualization.DataTable();
            data.addColumn('string', 'Year');
            data.addColumn('number', 'Sales');

            data.addRows(4);
            data.setValue(0, 0, '2004');
            data.setValue(0, 1, 1000);

            data.setValue(1, 0, '2005');
            data.setValue(1, 1, 1170);

  /* NEED TO MAKE THIS BAR RED? */
            data.setValue(2, 0, '2006');
            data.setValue(2, 1, 1400);

            data.setValue(3, 0, '2007');
            data.setValue(3, 1, 1030);


            chart = new google.visualization.BarChart(document.getElementById('visualization'));
            chart.draw(data, {width: 400, height: 240, title: 'Company Performance',
                              vAxis: {title: 'Year', titleTextStyle: {color: 'red'}}
                             });
}

Here is a code sample that changes the color. Note that the "colors" option accepts an array of strings.

var options = {
      title: 'Company Performance',
      hAxis: {title: 'Year', titleTextStyle: {color: 'red'}},
      colors: ['red','green'],
      is3D:true
};
