How to fill color to the vtkMRMLAnnotationROINode?

Support

I have created a ROI box as following code

        import SampleData
        sampleDataLogic = SampleData.SampleDataLogic()
        self.delayDisplay("Getting MR Head Volume")
        mrHeadVolume = sampleDataLogic.downloadMRHead()

        # Create clipping ROI
        roiNode = slicer.vtkMRMLAnnotationROINode()
        roiNode.SetXYZ(36, 17, -10)
        roiNode.SetRadiusXYZ(25, 40, 65)
        roiNode.Initialize(slicer.mrmlScene)

I want to fill color to the roiNode (such as blue color). Is it possible to do it? I have found some methods but it does not work.

See how it is done in Volume clip with ROI module (in Volume Clip extension). Probably the simplest is to set values in a labelmap volume (and then if you want you can import that into a segmentation node).
