Usually u can add new movieclip at root instead of root.Menu_mc to prevent autotint

To avoid tint of specific display objects in AS3 you may be able to get their transform.concatenatedColorTransform which contains the combined color transformations of that display object (and parents)
Then invert that matrix and apply the inverse transformation to the element you want to un-tint, should cancel out the original color transform
(haven't done this myself, its a theory that I've never tested out)
