text: **Extended Color Support**
  
  To support extended color spaces in Publisher, additional EMF semantic records and 
  
  interfaces are needed because EMF only supports RGB (red-green-black) colors. 
  
  Extended color spaces include CMYK (cyan-magenta-yellow-black) and spot color space, 
  
  which are commonly used in commercial printing.

  colors with color IDs in the EMF. The type for the color ID is**COLORREF**, which is the
