Setting the Screen Foreground Color

  The screen pattern, when set to anything other than the
  default pattern, consists of a screen foreground (the filled
  area in the pattern) and a screen background (the pattern's
  outline).  The selected pattern is displayed in the pattern
  viewer.

  To change the default screen color on a monochrome system,
  click on the White On Black radio button to reverse the fill
  and outline colors.

  To change the default screen color on intensity and color
  systems, click on the Screen Foreground Color button.  The

  Session Manager displays a color mixing dialog box.  For
  more information about mixing colors, click on Help in the
  color mixing dialog box.

  To see your new setting, click on Apply or OK.
