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.

RHUBARB ROOT GROUND ONLY
Dye Colour: Yellow Brown, Green (with Iron), Pink (with Soda Ash) – pH and Mordant Dependent | Country of Collection: China

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.

This lengthy process is well worth the effort for those seeking vibrant hues, especially for linen, cotton, and other plant fibres.

Colour Fastness: Poor to Medium

Colour Outcomes by WOF Ratio:

• 100% WOF Dye (Safflower): Soft yellow tones for protein fibres.

3. Strain the dye through cloth and add mordanted yarn or fibre to the dye bath.
4. Simmer for 1 hour and rinse to reveal a soft yellow colour.

Notes:

• Yellow is ideal for protein fibres, red for cellulose only.
• For richer red tones: Repeat soaking, kneading, and rinsing in a high pH environment.
• Safflower produces a softer, warm yellow dye but can yield red after more intensive preparation.

Embrace the natural beauty of Safflower dye and create stunning, soft yellow and red tones for your textile or paper projects.
