[GRASSLIST:5805] Easily generating colourtables

[Jose Luis Gomez-Dans]

Hi!
I want to plot three raster images side by side. They cover the same 
area, and are just to point out any obvious differences. In order to do 
that, the colourtables used needs to be identical. In GRASS, these are 
automatically calculated from the span of the data, and in my case, 
this is slightly different. I would like to set the limits of the 
colourtable to be the same. 
Is there an easy way to do this in GRASS, or do I have to modify the 
rastersthemselves with r.mapcalc (groan :D)?

Thanks!
José
