You just forgot to remove the line that says 
        pigment {rgb .9}
in some of the isosurfaces.

If you have two textures on an object, then they act as "layered
textures" (read the docs if you're unfamiliar with that concept) and you
see the opaque underlying {rgb 0.9} texture layer through the partially
transparent {White filter 0.7} texture layer.
