           Name of 3D raster map(s)

           Input file with one map name per line
           Input map names can be defined in an input file in case a large amount of maps must be
           specified. This option is mutual exclusive to the map option.

       r3.colors  has  exactly  the same functionality as r.colors but for 3D raster maps. Please
       refer to r.colors.


       r3.colors map=volume_1 color=gyr

       ColorBrewer is an online tool designed to help people select good color schemes  for  maps
       and other graphics.
