[GRASSLIST:2551] shade.rel.sh query

[Kevin Slover]

morning,
    I am trying (without success) to see what a color shaded raster will
look like, but am having very little luck at this time.  The problem I
seem to be having is that this cannot handle both neg and pos values in
the same raster??  Looking at the range, they are all positive values,
but the absolute values of the depths...is this true??  I have looked
through the code, and that is what it appears somehow...
also, is there a way to get a "gold" looking shade??
an example of the color scheme is such:

wondering if the hydrographers out there might have a scale for it already! Thanks!!
