Thuluth is the monumental display script of the Islamic world — each letter twice or three times the height of Naskh, with sweeping curves and elaborate flourishes that transform walls into pages. This system channels its Saudi state application: the deep green of the national flag as ground, imperial gold of the Kaaba kiswa as stroke, and cream parchment as reading surface.

The result is a design language of sacred grandeur — symmetric, generous, and unapologetically ornamental — suited to institutional identity, cultural publishing, and ceremonial communications.
