TECH Hueforge. Couple of notes, you can do this all with a single AMS, just be sure to swap the filament colors within the AMS after it has printed. Example, once black has printed place the Red within it's slot, same goes for turquoise and light grey, and finally dark grey will be replaced with White.

If slicing yourself I highly recommend changing wall generation from classic to Archane. It will take forever to slice, but it will make the quality a bit better.
