Gostaria de mudar a cor da barra no gráfico de Gantt com base no valor que estou passando. QuandoPercent done igual a mais de 100, a barra deve estar vermelha. É possível?

google.charts.load('current', {'packages':['gantt'], 'language': 'pt-br'});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

    var data = new google.visualization.DataTable();
    data.addColumn('string', 'Task ID');
    data.addColumn('string', 'Task Name');
    data.addColumn('string', 'Resource');
    data.addColumn('date', 'Start Date');
    data.addColumn('date', 'End Date');
    data.addColumn('number', 'Duration');
    data.addColumn('number', 'Percent done');
    data.addColumn('string', 'Dependencies');

    data.addRows([    
        ['C10', 'C10', 'Xa', new Date(2015, 3, 20), new Date(2016, 8, 30), null, 109, null],
        ['C15', 'C15', 'Xa', new Date(2016, 5, 2), new Date(2016, 9, 31), null, 111, null],
        ['C20', 'C20', 'Xa', new Date(2016, 8, 15), new Date(2016, 10, 25), null, 88, null],
        ['C21', 'C21', 'Xa', new Date(2016, 8, 1), new Date(2016, 10, 25), null, 90, null]
    ]);

    var options = {
        width: "100%",
        hAxis: {
            textStyle: {
                fontName: ["Roboto Condensed"]
            }
        },
        gantt: {
            labelStyle: {
                fontSize: 12,
                color: '#757575'
            }
        }
    };

    var chart = new google.visualization.Gantt(document.getElementById('chart_div'));
    chart.draw(data, options);
}
