Tiwi tutini (pukumani) poles are carved ironwood columns raised at mortuary ceremonies on the Tiwi Islands off northern Australia. Their black-primed bodies are painted in stacked horizontal registers of dotted lines and cross-hatch — hot red and orange ochre set against cooler yellow and white pipeclay, all carried on black.

This design system translates the upright banded pole into interface: a black ironwood ground, strict horizontal registers of dotted and hatched fill, and a flat matte ochre palette where yellow burnt in fire deepens toward orange-red. The ground is always dark — never cream.
