This AngularJS directive allows changing the color of dynamically loaded SVG files. Subject to same domain policy.

vod-svg.js

app.directive('vodSvg', function() {
  return {

    restrict: 'E',
    replace: 'true',
    template: '<object type="image/svg+xml" data=""></object>',

    link: function(scope, element, attrs) {

      var paintSvg = function (svgElem){
        var paths = [];
        ['path', 'circle', 'rectangle', 'polygon'].forEach(function(shape){
          paths.push.apply(paths, svgElem.contentDocument.getElementsByTagName(shape));
        });
        for(var i = 0; i < paths.length; i++) {
          paths[i].style.fill = getComputedStyle(element[0]).color;
        }
      };

      element.bind('load', function(e) {
        paintSvg(e.srcElement);
      });
    }
  };
});

Obg, isso me ajudou muito.
