Dithered mode uses a 4×4 Bayer matrix — it looks best for smooth color transitions like concrete gradients. View from a distance for the full effect.
Hard Cut divides the wall into clean bands of each block — great for bold geometric builds.
Striped alternates the two blocks in thin bands for a striped flag or banner effect.
Use relative coordinates (~) if you want commands that work from your current position. Switch to absolute if you know the exact coordinates.
For very wide walls, paste commands into a command block chain or use a datapack. The commands are ordered left→right so you can paste them sequentially.
Best block combos for gradients: Concrete shades (white→gray→black), Terracotta (orange→red→brown), Wool pastels (white→pink→purple).
