The original Moroder seems to be just colored in one color per scene (like the colorized Version of Murneaus Nosferatu) while the "Redux" seem to have some multi colored scenes.
The original has some multi-colored scenes too (like during the creation of Hel). From what I've seen, the Redux is supposed to be exactly like the original (only sourced from the remastered Kino version), but of course it isn't 100% perfect.
