Weld
Weld is the yellow dye plant Reseda luteola. Dye analysis of the "Salting" group of carpets proposed weld for their yellows, and the V&A records a luteolin yellow in a 16th-century Persian carpet fragment. Iranica and Edwards equate weld with Persian isparak, but present-day Isfahan dye masters name isparak as a larkspur and say they do not use weld.
