Weld (Reseda Luteola), is one of the oldest and most reliable natural yellow dyes in the world. Used across Europe and the Middle East since antiquity, weld is renowned for its brilliance, efficiency, and exceptional lightfastness. From sunny pale yellows to deep golden hues, weld has colored everything from medieval tapestries to 18th-century silks, and remains one of the clearest sources of yellow available to natural dyers today.

Our Weld Powder is carefully produced from Reseda plants selected for their high concentration of luteolin, the key yellow dye molecule. Weld is certified under the Global Organic Textile Standard (GOTS) for use on organic fibers. Weld is also prized for mixing with indigo to create emerald and leafy greens.

Active dye components: luteolin (flavonoid)
CI Natural Yellow 2
