Obviously all machined metals. Is refined too shiny? If yes than compact should do with it dirtier look.
Would stone of dark colour work if applied? Like Igneous purple ish color and it’s pattern. Or maybe metamorphic from Nasharil of the same color? Maybe if it’s brick?
All greyish so metamorphic brick that you used already building the road.
Compact coals I guess could be good choices?
Lanterns rather than gleam blocks I’d say. Unless gleam is hidden in a second layer of floor or wall and only seen in small parts through chiseled blocks. If yes what colors would work the best for the city?
For wood, should we limit it to roofs window frames and such?
