title: Changing colors of slices depended on text in the name
body: <p>I am using Highchart in my page and I wonder if I can make pie chart more dynamic. I want to make slices, where specific text in the name appears, to be shades of green.<br/><br/>
  Some code:</p>
  
  <pre><code>plotOptions: {
                      pie: {
                          allowPointSelect: true,
                          cursor: 'pointer',
                          dataLabels: {
                              enabled: true,
                              color: '#000000',
                              connectorColor: '#000000',
                              formatter: function() {
                                  return '&lt;b&gt;'+ this.point.name +'&lt;/b&gt;: '+ this.y;
                              }
                          },
                          showInLegend: true
                      }
                  },
                colors:['#89ABD5','#3b73b9','#22436b','#08a5e1',
                  ],
                  series: [{
                    color:'#89ABD5',
                      type: 'pie',
                      name: '',
                      data: []
                  },
                  {
                    color:'#3b73b9',
                      type: 'pie',
                      name: '',
                      data: []
                  },
                  {
                    color:'#22436b',
                      type: 'pie',
                      name: '',
                      data: []
                  },
                  {
                    color:'#08a5e1',
                      type: 'pie',
                      name: '',
                      data: []
                  },
                  ]
  </code></pre>
  
  <p>I have names like: <code>GOOD A, GOOD B, GOOD C, etc..</code>, <code>BAD A, BAD B, BAD C, etc..</code> and <code>OTHER1, OTHER2, OTHER3, etc..</code><br/><br/>
  What I am trying to achieve is when, there is a text GOOD in the name, the slices should be in shades of green, while BAD -> shades of red. Other slices should be by default.<br/><br/>
  Data is get through getJSON.</p>
