Another idea is to use PATTERN palettes, which are a bit more bold than
greyscales. Try this demo script to see how this looks, reading along
with the commands as they're executed:
yes? go pattern_demo
The Unix command-line Fpalette lists palette files available, so to
search for palette files whose names include "grey"
> Fpalette grey
and Fpattern returns a list of pattern palettes:
> Fpattern pattern
Here is an FAQ showing how to combine palette and pattern palettes and
draw a color key that combines both

Hi,
You can put the following line in the beginning of the code
palette=greyscale.spk
or
palette=grayscale.spk
check the FER_DIR/ppl directory for other palettes
This will use grayscale for your picture.

Hi,
Usually we make shading contour using fill, or shade in ferret, and
the picture is colorful. Now I am going to use black/white instead. How
can I convert the color figure to black/white one within ferret or with
unit command?
Thanks!
