WELD DYE (Reseda Luteola)
Dye Colour: Yellow and Green (when overdyeing) | Country of Collection: Typically Europe
Weld (Reseda Luteola) is a renowned plant-based colourant with a rich history, often used to create high-quality dyes in temperate regions. Paired with other traditional dye plants like Madder, Woad, and Dyer's Chamomile, it yields beautiful shades of yellow, which can then be overdyed with Woad to create the iconic Saxon and Lincoln greens. Legend has it that Lincoln Green was the signature hue of Robin Hood and his outlaws, achieved by overdyeing Weld yellow with Woad blue.

RHUBARB ROOT
Dye Colour: Yellow Brown, Green (with Iron), Pink (with Soda Ash) – pH and Mordant Dependent | Country of Collection: China
Rhubarb root is a captivating natural dye, producing a spectrum of colours that vary depending on the pH of the dye bath and the mordant used. Known as a Quinone dye, it is rich in tannins, which yield earthy yellow-brown and green hues with iron. A higher pH will shift the colour to delicate pinks or reds, though these tones are less colourfast. Notably, the yellow and green shades are more stable, maintaining their colour for longer.

SAFFLOWER DYE (Carthamus tinctorius)
Dye Colour: Soft Yellow and Red | Country of Collection: Iran
Safflower, a thistle-like plant native to arid environments, offers a stunning soft yellow and red dye, making it a great choice for dyeing natural fibres like linen and cotton. While it produces a warm red, the process to extract this colour is intricate, requiring extended soaking, kneading, and rinsing. By adjusting the pH and repeating these steps, you can achieve a richer red tone on plant-based fibres. This lengthy process is well worth the effort for those seeking vibrant hues, especially for linen, cotton, and other plant fibres.
