Colour from the ground

Madder root, indigo and oak instead of azo dyes — what natural dyeing means for the colour of your socks, and for the water it leaves behind.

Natural dye baths with madder root and earth pigments beside drying cotton

Conventional dyeing is fast, cheap and thirsty. A single conventional dye run can leave behind water that has to be treated before it goes anywhere near a river. We took the slower route instead.

Our colour comes from madder root, indigo, oak bark and earth pigments, in closed-loop baths that reuse the same water across several runs. There are no azo dyes and no heavy metals in the process.

Why the colours shift

Plant dyes are not printer inks. A harvest of madder from one year is a little warmer than the next, so two batches of the same clay tee are close relatives rather than identical twins. We think that is the point.

Colour settles as you wear it. Expect a gentle softening over the first months, then years of very little change if you wash cool and dry in the shade.

What it costs us

Natural dyeing takes longer and yields less per run than synthetic dyeing. We accept the smaller batches because the alternative is a garment that costs the water table more than it costs you.
