[GRASSLIST:4941] r.colors

Hello everyone,

          I need to change the color table of a raster map layer
          in a non-interactive way.

          I tried r.colors map=mapname color=rules
                  > 34 100 45 234
                  > end

                  here, 34 --> catagory value
                        100 --> red_value
                         45 --> green_value
                        234 --> blue_value

   The output is a raster layer where category 34 has R=100 G=45 B=234
and the rest of the catagories display white color R=255 G=255 B=255.

   However, my intension is to get a raster layer where, category 34
has R=100 G=45 B=234 and the rest have their original RGB values.

bye
