+<h3>The Process</h3>
 
 Each map cell is processed individually. First, the working
 color is set to the color of the corresponding cell in the
-map layer chosen to represent <EM>HUE</EM>.  Second, this
-color is multiplied by the <EM>red</EM> intensity of that
-cell in the <EM>INTENSITY</EM> map layer.  This map layer

+color is multiplied by the <i>red</i> intensity of that
+cell in the <i>INTENSITY</i> map layer.  This map layer
 should have an appropriate gray-scale color table
 associated with it. You can ensure this by using the color
 manipulation capabilities of
-<EM><A HREF="d.colors.html">d.colors</A></EM> or
