text: Q:
  
  Highcharts assign colors to series after using csvURL
  
  I'm importing a csv file using Highcharts cvsURL for a line chart. I'm using styledMode and I defined the default colors. Highcharts is using my stylesheet. Is there an easy way to tell each series which color to use?
  I have lots of lines, so highcharts cycles through its 10 default colors. I need one of the colors to only be assigned to 2 specific series though. 
  Here is my code so far:
  Highcharts.chart('container', {
      chart: {
          type: 'line',
          styledMode: true //this totally separates the design from the svg.
      },
      data: {
          itemDelimiter: ',',
          csvURL: 'http://deq.at.utah.gov/wp-content/themes/deq/parts/charts/Ozone-4th-Highest-8hr-Front.csv'
      },
      title: {
          text: 'Ozone 4th Highest 8-hr Concentration Wasatch Front'
      },
      yAxis: {
          title: {
              text: '(Ozone PPM)'
          }
      }
  });
  
  I think the API said something about assigning classes to a series. Maybe that would work because I could make custom CSS for only those series, but I can't see how to do that using csvURL. 
  
  A:
  
  You can define color or className for series in this way:
  data: {
    csvURL: '...'
  },
  series: [{
    color: '#00c735'
  }, {
    color: '#c4392d'
  }]
