A type of phulkari made on a neela khaddar, or base cloth, dyed with indigo, the nilak phulkari is characterised by red and yellow embroidery. A small amount of iron is sometimes added to the indigo to generate a darker shade of blue. Unlike chopes and suber phulkaris, nilak phulkaris are never used in wedding rituals.

The blue and black shades of nilak phulkaris have been variously associated with Krishna, who is depicted with blue skin, or the neelambari musical raga, which represents longing. Young girls in Punjab sometimes begin making simple nilak phulkaris before they make more elaborate or ritually significant embroidery.
