<h2>DESCRIPTION</h2>
<em>r.rgb</em> generates separate red, green and blue maps from a
raster map and its associated color table (grey255).
<h2>EXAMPLE</h2>
<div class="code"><pre>
g.region raster=elevation -p
r.rgb input=elevation red=elevation.r green=elevation.g blue=elevation.b
</pre></div>
<p>
In this case <em>r.rgb</em> produces in the current mapset three new
raster maps - 'elevation.r', 'elevation.g', 'elevation.b'.
