Hi, I have a segmented volume with 4 different phases. Each phase has a different value from 0 to 4 in the histogram.

When I try to upload the volume (saved as .mrrda) it appears in black and white only. When in ImageJ has 4 different colour. (See the image attached)

The thing is that I want to tenderize the segmented volume in 3D Slicer, giving each phase a different color.

Do I have to apply a threshold to the segmented volume?

When you load in Slicer, try picking Segmentation instead of the default Volume.
