body: <p>I changed the color over the line of the navigator: color: <code>'rgba(255, 255, 255, 0.00)'</code>
  and I changed the color of the line: <code>lineColor: 'red'</code>
  it is my <a href="http://regexinfo.ru/my_infa/chart/chart_good_scale1.php" rel="nofollow">chart</a></p>
  
  <p>but I can not change the color under the line of the navigator: <a href="http://regexinfo.ru/my_infa/chart/change_color.JPG" rel="nofollow">ScreenShot</a></p>
  
  <p>all code of the navigator:</p>
  
  <pre><code>navigator: {
      maskFill: 'rgba(255, 255, 255, 0.45)',
      series: {
          type: 'areaspline',
          color: 'rgba(255, 255, 255, 0.00)',
          fillOpacity: 0.4,
          dataGrouping: {
              smoothed: false
          },
          lineWidth: 2,
          lineColor: 'red',
          marker: {
              enabled: false
          },
          shadow: true
      },
      yAxis: {
          reversed: true
      }
