You can get the color table as follows:

  ScalarMap rgbMap = new ScalarMap(..., Display.RGB);
  . . .
  ColorControl control = (ColorControl) rgbMap.getControl();
  float[][] table = control.getTable();
  // now save the table with the image

I don't know enough about your file format to know how
you'd save the color table, but at least this code shows
you how to get the table information from VisAD.

Good luck,
Bill
