>However when I load an image into Paraview, the slices don't show up as RGB. I think the data is being written correctly. To verify this, I took the same binary data (the contents of the nii file minus the 352 byte header), and added a Meta header:

>ElementNumberOfChannels = 3
>ElementType = MET_UCHAR
>ElementDataFile = LOCAL

>The resulting image displays correctly as RGB. Unfortunately, the geometry of the image is often confused by the conversion between nii and mha files, so it would be really helpful if I could load RGB .nii images directly. Is there a way to read RGB images in NIfTI-1 format?
