[GRASS-user] Changing colour tables

[pawan datta]

Dear All,
I am having problems with changing color rules for a raster map. I 
have three different DEM's obtained from different sources and i 
have set the color for each as predefined color rule 'contour'. My 
problem is that I want to have all the 3 DEM's use the same color 
scheme i.e., each height range (700-800m, 800-900m and so on) in 
all the rasters is represented by the same color. Could somebody 
please help me with this. Also, I want to change the color table 
so that it uses absolute values instead of relative values.
Thank You very much in advance..
