I should be able to give you a positive answer concerning that in an
hour of so.  So stay tuned.

Those calls are exactly correct.  See examples/c/x16c.c.

However, they must be placed in your code in the correct place.
See that example.

Another possibility instead of hard-coding color maps in your code 
is simply to use command-line options, e.g.,

-cmap0 cmap0_black_on_white.pal -cmap1 cmap1_gray.pal

when you generate your plots.
