The indigo dye had a big influence on port cities of the Arabian Gulf. Indigo shipments, coming from India and heading to the rest of the world, frequented the region. This gave birth to the use of the dye in fabrics ranging from attire to household linen. People would usually dye their clothes and not wear very bright colours to hide its dusty or dirty appearance. A variety of dyes were used and indigo was one of them. In the picture, a lady can be seen dyeing fabric with the indigo dye.
