Oh, and to avoid the gradient issue on color changes, the solution is easy, 
the print job would pause on a color change, and the plastic would be 
purged on an unused area of the build plate until the desired color is 
extruding, at which point the print job would resume, You would require 
some sort of chromatic sensor to determine when the correct color was being 
extruded to make this work.
