--help

Print usage summary

--verbose

Verbose module output

--quiet

Quiet module output

--ui

Force launching GUI dialog

Parameters:

map=name[,name,...]

Name of 3D raster map(s)

file=name

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.

DESCRIPTION

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

EXAMPLES

r3.colors map=volume_1 color=gyr
