This is a single color print, although I manually interjected a color change layer for the numbers.
The author remixed this model.
Unfortunately there was an error with the .3mf file from the original upload, and the original author never resolved it. So I did a workaround and was able to load the .3mf file into Orcaslicer, removed several negative parts that were throwing errors, exported it as an .stl, loaded it into Tinkercad, then basically re-created the dashboard in Tinkercad using just the recessed numbers section from the original file as the starting point. It now works for loading into PrusaSlicer.
