Vamos agora ver as configurações / etapas adicionais realizadas.

cores

Configure as cores de cada torta usando o Highcharts.getOptions().plotOptions.pie.colors propriedade.

// Make monochrome colors and set them as default for all pies
Highcharts.getOptions().plotOptions.pie.colors = (
   function () {
      var colors = [];
      var base = Highcharts.getOptions().colors[0];
      var i;

      for (i = 0; i < 10; i += 1) {
         // Start out with a darkened base color (negative brighten), and end
         // up with a much brighter color
         colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());
      }
      return colors;
   }()
);
