Reseda luteola Weld is also known as Dyers Weld, Dyers Rocket, and Dyers Mignonette. It produces an excellent light and washfast yellow and is a strong clear yellow to combine with indigo for emerald and leaf greens. Traditionally cultivated throughout Europe as a yellow dyeplant it still flourishes on embankments or beside railways and roads. Weld gives strong intense yellows which are clear and bright. The strength of these colours makes weld a good choice for overdyeing with indigo to obtain teals and greens.
