The rules file needs to be in the $GISBASE/etc/colors/ directory. I just
added a few more: terrain, bcyr, slope, and elevation. You can try
copying over the four example files from src/raster/r.colors/cmd/ as
well, some are nice.

The GUI and man page will be updated at some point to cover both these
issues..
