Bart,

    The pinkish color you refer to is most likely the copper alloy. 

    It is best to use a coating on the work such as Alcohol and boric
    acid to protect from firescale.  It is also important to stop and
    Pickle the piece often if you are doing a lot of work on it. 

    The lower the karat of the gold the more obvious this problem
    becomes if you are heating the piece multiple times without Pickling
    and cleaning the piece. 

    Pickle will only remove the surface oxidation. If you have overheated
    the metal and the oxidation goes deep into the metal you will have to
    take drastic measures to remove it such as Stripping or Bombing and
    even then it may not remove the oxidation if it is extremely deep. 

Good Luck
