You all made good points about Ichigo's elemental Zanpakuto, but I think that his spirit energy color is black is purely because the writer of the Manga knew that in Aura's, black means mystery or to hide something. True it also means darkness but Ichigo has always had hidden power so that is why I think his spirit energy is black.
