      OOXML spec says if this exists it must have all indexes.

      From the OOXML Spec, Part 1, section 18.8.27:

      This element contains a sequence of RGB color values that correspond to color indexes (zero-based). When using the default indexed color palette, the values are not written out, but instead are implied. When the color palette has been modified from default, then the entire color palette is written out.

      Parameters:
      colors - CTColors from styles.xml possibly defining a custom color indexing scheme
      Returns:
      custom indexed color map or null if none defined in the document
