 <em>v.colors</em> allows the user to create and/or modify the color
 table for a vector map. The vector map (specified on the command line
 by <b>map</b>) must exist in the user's current mapset search path.

 As input a vector map with a numeric data column is required which is
 used to apply the color rules. The color values are stored in a string
-column (default name "GRASSRGB") by saving the R:G:B values suitable
-for use with '<tt>d.vect -a</tt>'.
+column (default name "GRASSRGB", varchar(11)) by saving the RRR:GGG:BBB
+values suitable for use with '<tt>d.vect -a</tt>'. If this RGB column
+is not found in the attribute table, it is automatically created.
 
-<P>
+<p>
 How it works: it creates a dummy raster map with the same data range as
 the vector's column then runs <em>r.colors</em> for that temporary map.
 It then uses <em>r.what.colors</em> for each value found by <em>v.db.select</em>
 and uploads it a new column in the vector map's attribute database.
 
-<P>
+<p>
 It is planned that this script will be replaced with a C display module which
 renders thematic vector maps directly instead requiring the overhead of
 saving the colors into the DB.

 If the target column name given by the <b>rgb_column</b> option does
 not exist, it will be created. The default name is "<tt>GRASSRGB</tt>".
