  \class SoSFColor SoSFColor.h Inventor/fields/SoSFColor.h
  \brief The SoSFColor class is a container for an SbColor value.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store a single color value (i.e. Red + Green + Blue).

  Fields of this type stores their value to file as a "R G B" triple
  component, where each color component value is between 0.0 and 1.0.
