sampleObj.colors.r = 100;
sampleObj.colors.g = 178;
sampleObj.colors.b = 245;
$scope.obj = sampleObj;
$scope.copiedObj = {};
$scope.changeObjectToJSON = function() {
angular.copy($scope.obj, $scope.copiedObj);
}
});
</script>

<body>
<br><br>
<div ng-controller="AppController">
<button ng-mousedown="changeObjectToJSON()">
Click this button to create a copy of the object
</button>

NOTE: using angular.copy makes the copy a total different object (not a reference)

source object: {{ obj }}

copied object: {{ copiedObj }}
