The wood from the barberry stems and roots can be cooked in water to extract a strong yellow dye.

Style of textiles, particularly village floor coverings, that are handwoven in the vicinity of Bergama, western Turkey, or brought there for market from the interior of the country. Although most Bergama carpets date from the 19th and 20th centuries, rare examples survive from the 17th century. They are characterized by bold, highly varied patterns often in red, blue, and white. Typical designs include rows of panels or central medallion designs, preserving the fashions of much earlier centuries. The format of Bergama carpets is usually more nearly square than other Turkish types, and the few known prayer rugs tend to be unusually small. The red dye used in this area sometimes causes the pile to erode and look as if it had been cut in relief.
