   I think you missed my question on the same subject from late last week.

   You want a legend of the category colors for your shaded relief map?

   First, the shaded relief map is always in greys; from the Description
section in the man page, "The map is assigned a grey-scale color table."

   Second, if you want to drape a colored map on a 3D base use d.shademap
("d.shadedmap - Drapes a color raster over a shaded relief map using d.his".)

   Third, within ps.map use the colortable stanza to present a legend of
raster category colors.
