Voxels with a texture index vs. voxels with a color index is not really a big distinction in my eyes. They're both integers. The way in which you resample them, as well, is not invalidating. Otherwise "pixel art" would also be invalid as it's built around display output methods that are not mathematically correct(NTSC signal, square LCD pixels, etc.).
