title: How do you set pie chart colors in angular-chart.js
body: <p>I am playing with the pie chart in <strong>angular-charts.js</strong>. I have made it so that I can set the data and labels. A watcher function executes whenever something is added or removed from the list of "pie" items.</p>
  
  <p>Labels and data are recognized, but not the color. I have tried a few different spellings.</p>
  
  <pre><code>app.controller("PieCtrl", function ($scope, $timeout, pieItems) {
      $scope.labels = pieItems.labelsItems();
      $scope.data = pieItems.data();
  
  
      function watcherFunction(newData) {
          $scope.labels = pieItems.labelsItems(); //just an array of strings. 
          $scope.data = pieItems.data(); //just an array of number values
  
          $scope.colours = ["rgba(224, 108, 112, 1)",
              "rgba(224, 108, 112, 1)",
              "rgba(224, 108, 112, 1)"] //not working
  
          $scope.colors = ["rgba(224, 108, 112, 1)",
              "rgba(224, 108, 112, 1)",
              "rgba(224, 108, 112, 1)"] //also not working
  
      }
  
      $scope.$watch(pieItems.list, watcherFunction, true);
      $scope.$watch(pieItems.getTitle, watcherFunction, true);
  
  });
  </code></pre>
  
  <p>It seems to generate random colors for the slices. I would like to override this. Surely it must be possible to do this?</p>
