<p>[QUOTE=&quot;bdunnse, post: 2619005, member: 57317&quot;]Can you tell if the red is due to thickness versus density? obviously in this picture we know the red is due to the thickness. But I would expect the material in the devices (i.e. Lincoln&#039;s big fat noggin) to be less dense than the fields yet the devices are green and the fields are blue. In other words the color variations seem only to be an indication of thickness not density. Just curious.[/QUOTE]</p><p><br /></p>
