Stone is a gray stone block and a common main material in many styles. Pair it with wood for warmth and a darker block such as deepslate for foundations and trim.
Blocks to try around it, picked by color and surface detail. These are suggestions, not rules.
Plain stone can look flat across a large wall, so mix in some cobblestone and set the walls on darker cobbled deepslate. Spruce logs at the corners give the gray a warm edge.
Ranked by the average color of each block's texture. A close color is a starting point for a palette, not a rule.
