You could always insert an extra column and so it will have different color. Thats all that can be done I guess.

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

            data.addRows(4);
            data.setValue(0, 0, '2004');
            data.setValue(0, 1, 1000);
            data.setValue(0, 2, 0);

            data.setValue(1, 0, '2005');
            data.setValue(1, 1, 1170);
            data.setValue(1, 2, 0);

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

            data.setValue(3, 0, '2007');
            data.setValue(3, 1, 1030);
            data.setValue(3, 2, 0);


            var chart = new google.visualization.BarChart(document.getElementById('visualization'));
            chart.draw(data, {width: 400, height: 240, title: 'Company Performance',
                              vAxis: {title: 'Year', titleTextStyle: {color: 'red'}},
                              series: [{color: 'blue', visibleInLegend: true}, {color: 'red', visibleInLegend: false}]
                             });
}
