Voxel Data In Color

I am following this tutorial on importing MRI Scan Data (sequenced of images)

It works on the corpse slices, but I can’t seem to get the color imported into voxel. Is this a limitation of current version Blender? Is there way around to get voxel color data?

Is there a good thread on Voxel Data and Point Cloud Data

Thanks.

The answer seems like: no color data got imported in.
