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.
苏鲁斯体是伊斯兰世界最宏伟的展示书体——每个字母高度是纳斯赫体的两到三倍，笔画舒展、装饰繁复，将墙壁化为书页。本设计系统取材其在沙特阿拉伯国家视觉中的当代应用：以国旗深绿为底色，以天房帷幕的帝王金为笔触，以奶油色羊皮纸为阅读面。
最终呈现的是一种神圣庄严的设计语言——对称、大气、毫不掩饰的装饰性——适用于国家机构形象、文化出版及礼仪性传播。
