title: Highcharts change label text for a single series
body: <p>In my stacked bar highchart you will see that I have set my last series to the color grey. Is there any way to set the text color to black where the series background color is grey?</p>
  
  <pre><code>plotOptions: {
      series: {
          stacking: 'percent',
      },
      bar: {
          stacking: 'percent',
          dataLabels: {
              enabled: true,
              format: '{y}%',
              style: {
                  color: '#ffffff' //This is where i set the color to white
              }
          }
      }
  }
  </code></pre>
