[lxurjlhn] Stickerless cuboid

In a cuboid, one sees the inside facets of cubies far more frequently than in a regular Rubik's cube.  Stickerless provides the ability for the inside facets to be a useful color.  (Stickers would peel off due to the constant rubbing of adjacent layers.)  However, this requires a coloring scheme which assigns a useful color to an inside facet.

Most obvious is for the color to be that of the corresponding parallel outside face when solved.  Coloring the inside cubies might provide an additional challenge of getting them oriented correctly.

For even sized cuboids, the Crazy Pill demonstrates coloring each octant uniformly one color.
