         Almost - you can go into the AIPS PostScript file made from
LWPLA and add

1 0 0 setrgbcolor

right after the 

newpath gsave 

line, then all lines will be in red and all text and grey-scales will
still be in black->white.

You can experiment with putting it later in the file to get only the
contour lines in red.  The PostScript files are really pretty simple
in structure and easy to edit.
