Oxford Biocolours began by accident in a lab.

Founders Jim and Darren were deep in the science, developing plant-based dyes that didn’t fade, bleed, or pollute — no mordants, no compromises.

The twist? Yarn samples kept disappearing. Jim’s wife had a crochet hook and a habit of testing the experiments herself. Her creations were beautiful and brought the colours to life.

That’s when we knew this was too good to keep hidden in the lab. For us, this wasn’t just chemistry anymore. It was craft. It was connection. It was yarn we wanted to create.

At Oxford Biocolours, we’re building a new standard for colour. One where sustainability doesn’t mean sacrifice — and natural doesn’t mean dull.

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