Output Color Settings
  You can choose one of these Output Color options:
  -   Black and White
  -   Color
  -   Gray Scale
  Only the settings applicable to your workstation appear.  Any
  workstation can take Black and White snapshots.
  If your workstation has a color monitor, you can select any
  Output Color option.  However, choosing Black and White
  on a color monitor may cause certain details of X-client
  applications to become just white spaces in the output file.
  This is due to the color loss during the color-to-black-and-
  white dithering process.  Choosing Gray Scale in this case
  would produce a better image since the image would be
  dithered in an attempt to preserve the contrast.
  If your workstation has a gray scale monitor, you can select
  Gray Scale or Black and White.
  For more information, double click on any bold hotspot.
