Weld Extract (Reseda luteola) – Natural Yellow Dye

As an extract, it offers faster preparation, easier storage, and more efficient use compared to raw weld—ideal when you want clean, repeatable yellows with less dyestuff and less setup time. Botanical name: Reseda luteola Color range: bright, clean yellow to warm golden yellow; with iron, olive/khaki shifts. Best for Wool & silk with alum mordant Cotton & linen (tannin + alum recommended for strongest, clearest yellows) Eco printing / botanical dye workflows Greens when overdyed with indigo (clear lime-to-leaf greens) Olive/khaki tones using iron as a modifier   Dye-ready fabric suggestion: For clean, even results, try it on our undyed cotton fabric: [Undyed 100% Cotton Fabric] Extract vs raw material Extract is highly efficient: you typically use significantly less than raw plant material, with faster setup, easier filtering, and more consistent repeatability—
