So I gave Hueforge a try. This is my first print with it. The layers which you change colors should be included in the project, just write a comment if it is not. If you use AMS you can remove the pauses in the project. Those are for people without AMS like me, who want to switch colors manually.

Black

Galaxy Black

Cool Gray

White

Printed with Uzy brand filament. You can change filament colors inside the project to see different colored outcomes in silicer.
