DESCRIPTION
r.rgb generates separate red, green and blue maps from a
raster map and its associated color table (grey255).
EXAMPLE
g.region raster=elevation -p
r.rgb input=elevation
In this case r.rgb produces in the current mapset three new
raster maps - 'elevation.r', 'elevation.g', 'elevation.b'.
