[GRASSLIST:9408] color talbe (r.colors with rules)

[Luigi Ponti]

Hello,

I am trying to create a color table for a raster map which is the result 
of an interpolation via v.surf.rst. I am using r.colors (6.1 cvs on 
cygwin) in the following way:

*r.colors map=*/interpolated_raster /*color=*/rules/

When I enter no matter what color name and press enter, I receive the 
following message:

** bad color specification **
** rule is not added **

What am I doing wrong? I would like to get a color map that goes form 
blue to red.

Ciao,

Luigi
