Undyed khadi is the hand-spun, hand-woven cotton that Gandhi made the emblem of swadeshi self-reliance, turned on the charkha spinning wheel in village India between 1900 and 1950. In its raw state it is a cool natural greige — between dove grey and oatmeal — flecked with gray cotton slubs.

This system distills that cloth into an interface: a quiet greige ground, muted flax and slub neutrals, plain humanist sans type, and the honest, irregular texture of a handmade weave. Modest, not luxurious; homespun, not machined.
