Cracked Polished Blackstone Bricks is a damaged-looking version of a brick or tile block, for ruins and worn walls. Scatter it through the matching uncracked blocks rather than building a whole wall from it.
Blocks to try around it, picked by color and surface detail. These are suggestions, not rules.
Ranked by the average color of each block's texture. A close color is a starting point for a palette, not a rule.
