Model printed with six filament colors on the Prusa INDX upgrade for the CORE One+.
The filaments used were all Prusament PLAs:
Prusament Galaxy Black
Prusament Gentlemen's Grey
Prusament Royal Blue
Prusament Azure Blue
Prusament Vanilla White
Prusament Viva La Bronze.

The colors in the G-code preview are a bit exaggerated to make remapping colors on the printer easier.
Print at 0.15mm layer height for a reasonable amount of detail. No supports needed.
The model was created in Blender by mapping the original painting (slightly adjusted at the edges for a more "seamless" transition) as a texture onto a vase. This was also used as a displacement map for the texture.
The colors were then baked onto the vase and exported as a 3MF file using this powerful community Blender addon: https://extensions.blender.org/add-ons/threemf-io/
The author marked this model as their own original creation.
