Type: Procedure
Use: OKCOLORS sets the LWPLA adverbs DOCOLOR to 1 and PLCOLORS to
     colors which will use less ink than the standard TV colors.
     Mostly this means a white background and some contrasting
     colors.  This procedure works whether or not you have a TV
     running.  It sets PLCOLORS to
        PLCOLORS =0.3,0,0, 0.06,0.5,0, 0.5,0.33,0.5, 0,0.6,0.6
        PLCOLORS(1,9) ~ 0.3,0,0, 1,1,1
Output adverbs:
  DOCOLOR.....Set to 1.0 to tell LWPLA to use PLCOLORS.
  PLCOLORS....Line types 1-4 get colors dark red, dark green, purple,
              and dark cyan.  Types 5-8 ("dark" vectors) are black;
              Type 9 (labeling) is dark red, and the background is
              white.
