Oxford Biocolours

British wool, plant-dyed with world-first science. Yarn that won’t fade.

Oxford biocolours brings lab-developed, plant-based dyes together with British wool and skilled dyeing partners to create yarn that’s bold, reliable, and genuinely better for the planet.

Here to prove that sustainable colour doesn’t have to be dull — and that great yarn can be kind, clever, and a little bit rebellious.

If you believe great yarn can be kind to the planet and bold on the needle (and hook!), you’re in the right place.
