紫（zi）
Name meaning
紫 (zi) means purple, the deep color associated with dignity, auspicious signs and refined visual richness. In a given name it should suggest elegance and cultured brightness rather than status display.
Practical naming use
Use 紫 (zi) when the name should feel elegant, auspicious and visually memorable. It suits artistic, literary, ceremonial or public-facing identities. Pair it with a character that adds clarity, restraint or moral direction so the color image stays cultured.
Pair 紫 (zi) with a calmer character such as 紫安 (Zian) Zi'an, 紫文 (Ziwen), 紫清 (Ziqing) or 紫明 (Ziming). Avoid stacking it with too many treasure, glory or color words.
紫安 (Zian): Zi contributes purple, noble color; An adds peace, safety.
