3-component RGB images appear correctly in slice views and the slices can be displayed in 3D view, too.

4-component RGBA images are required for color volume rendering but RGBA volumes, but slice views of such volumes cannot be displayed in 3D view - see [this issue](https://github.com/Slicer/Slicer/issues/4939). If you want this to be fixed then [add a vote for it](https://discourse.slicer.org/t/about-the-feature-requests-category/30). If an issue gets many votes (or needed for a funded project) then we can allocate developers to fix it. If you need it sooner and you are comfortable with C++ and the VTK library then then you can give it a go and fix it (we can help if you decide to try it). You can also submit a feature request for volume rendering to support RGB volumes (without the need for manually extending it to RGBA).
