DESCRIPTION

       t.rast.colors computes a color table based on all registered maps of a space  time  raster
       dataset  and  to  assign  this  color  table  to  each map.  Hence the created color table
       reflects the data range of the space time raster dataset. This module is a simple  wrapper
       around r.colors.  All options of r.colors are supported.  Internally a file with map names
       is created and passed to the file option of r.colors.

       Please have a look at the r.colors manual page for further information.
