modify line color/width of ResliceCursorWidget

Dear community,
what is the propper approach to modify the color and width of the center lines of a reslice cursor?
I have noticed that vtkResliceCursorLineRepresentation provides access to the vtkResliceCursorActor, which has a method to modify the centerline properties, but where do the default colors (red, green, blue) come from?

Thanks for your help.

Finally, I managed to change the color and line width.
So, for exmple:

vtkResliceCursorLineRepresentation lineRep = new vtkResliceCursorLineRepresentation();

vtkProperty prop = lineRep.GetResliceCursorActor().GetCenterlineActor(0).GetProperty();
prop.SetSpecularColor(1,1,0);
prop.SetDiffuseColor(1,1,0);
prop.SetEdgeColor(1,1,0);
prop.SetVertexColor(1,1,0);
prop.SetLineWidth(3);
prop.Modified();

did the trick. I missed to call Modified() and had to set SpecularColor, DiffuseColor, EdgeColor… instead of just Color.

If there is a better way, please let me know.

Best regards,
Tom
