What it means
نیلی (nili) describes the colour indigo or a deep, saturated blue. The root is نیل (nil), referring to both the indigo plant and the blue-black dye extracted from it. The word is inherited from Middle Persian nīl, which in turn came from Sanskrit nīla, meaning dark blue. Persian did not borrow نیل from Arabic; the word travelled the other direction, out of the Persian-Sanskrit lineage. Today نیلی sits between آبی (âbi, blue) and بنفشهای (violet) on the colour spectrum and is closer to B1 level because learners at A1 typically learn آبی first. نیلی covers the indigo range of the visible spectrum, while سرمهای (sorme-i, navy) covers darker blue-greys.
How to use it
- آسمون شب نیلیه. (âsemun-e shab nilihe) “The night sky is indigo.”
- یه شال نیلی خریدم. (ye shâl-e nili kharidám) “I bought an indigo scarf.”
- رنگ درِ قدیمیه نیلیه. (rang-e dar-e qadimi-ye nilihe) “The colour of the old door is indigo.”
- نیلی و آبی خیلی به هم نزدیکن. (nili va âbi kheyli be ham nazdikand) “Indigo and blue are very close to each other.”
Cultural note
Indigo was one of the most prized dyes in the ancient and medieval textile trade, and Iran sat at the crossroads of the routes that moved it from South Asia to the Mediterranean. Traditional Persian carpet weavers valued نیلی tones for the depth they gave to geometric and floral patterns. The famous tilework of Isfahan mosques, whose colour is often described as نیلی or فیروزهای (turquoise), draws on this same tradition of using deep blues as a spiritual and aesthetic focal point in sacred architecture.
