Al-Qatt Al-Asiri is wall painting made by the women of the Asir highlands for the guest rooms of their own houses. White gypsum is plastered onto the wall, and over it go stacked horizontal bands — triangles, combs, rhombuses, banded squares — each ruled to a straightedge and filled freehand in flat opaque colour.

Roughly seven pigments work a single wall, every one from a named material: charcoal, iron stone, sedimentary rock, turmeric, pomegranate peel. This system keeps that logic — a plaster page, hard-edged colour fields, charcoal outlines, no shading anywhere.
