Hi Glynn,
I guess I wasn't very clear on this.

Heavens NO! No interactive mode. I just meant that currently the rules
option only allows you to specify the names of color table files located in
$GISBASE/etc/colors. My suggestion is to allow you to specify color table
files located anywhere. For example

...as we have now

r.colors map=elevation rules=byr

...as I suggest, the following would be permitted

r.colors map=elevation rules=/Users/cmbarton/colors/byr

When I was talking about a prompt, I meant the gui-prompt in the
interface-description xml file. Currently, it calls a list of values that
are the names of text files in the $GISBASE/etc/colors directory. As I
suggest, this would be replaced by a file browsing prompt (#prompt
file,file,file for scripts).
