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
