this is for kevin's request.
not a solution,
just a proof of concept ... (without important details)

to color the wall you can re-define l_wall with a code metapost in the
layout, passing the R,G,B values after the path.
next set the layout color map-fg altitude to have the altitude stored in
the scraps.
(see sample thconfig)

finally have therion write the parent scrap R, G, and B, after the wall
path, and use 0,0,0 when it writes the scrap.
(see howto)

i'm attaching also the output cave.pdf.

...

i'm not sure how useful wall-coloring may be ... anyways i leave up to
therion developers whether to add a layout option to color wall, map-fg, or
both.

cheers, marco
