So here is my module:
It works by creating 5 internal buffer polygons of decreasing size and then setting decreasing opacity to provide the fade effect.
It has been pointed out since I wrote this that it is also possible to use negative buffers, which would be another way to create the internal polygons.
How I set the colors so that no adjacent counties have the same color is a post for another day...
