  \class SoMFColor SoMFColor.h Inventor/fields/SoMFColor.h
  \brief The SoMFColor class is a container for SbColor values.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store multiple color values (i.e. "Red Green Blue"
  triplets).

  This field supports application data sharing through a
  setValuesPointer() method. See SoMField documentation for
  information on how to use this function.
