I can believe that the effect is only temporary--the action simply 
cannot go any deeper than a few microns.  All of which goes to show that 
if you want a more permanent color, there's always paint.  I have 
equipment that's made from high-density polyurethane foam (no special 
dies or forms needed for injection molding) finished with a coat of 
paint that's more than 30 years old.  It looks as good as the day it was 
delivered.
