[GRASS-user] Color table

I'm using the script r.colors.stddev and making some adjustments for my

First, I set all 0 values to null (r.null), then I run the modified script,
with this color table:

     r.colors "$GIS_OPT_INPUT" color=rules << EOF
       nv black
       0% black
       $MEAN_MINUS_2STDEV black
       $mean 136 136 136
       $MEAN_PLUS_2STDEV white
       100% white

But the null values don't become to be displayed black, they still white.
So, for my purposes, I will need re-convert null values to 0.

Is there a better way?
