 <H2>DESCRIPTION</H2>
 
-<EM>v.colors</EM> is much like <em>r.colors</em>, but may be used for vector maps.
-You give it a vector map and numeric data column, together with color rules
-like you would do for a raster. It creates a new column in the database with
-R:G:B values suitable for use with '<tt>d.vect -a</tt>'.
+<em>v.colors</em> allows the user to create and/or modify the color table for a
+raster map layer. <em>v.colors</em> is much like <em>r.colors</em>, but may be
+used for vector maps.
 
+As input a vector map with a numeric data column is required. It populates this
+column in the database with R:G:B values suitable for use with '<tt>d.vect -a</tt>'.
+
 <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.

 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>".
