Mo hom is Phrae's indigo work shirt: *mo* the fermentation pot, *hom* the plant. The cloth is never patterned and never printed. Its depth is arithmetic — one dip, dry, oxidise, dip again — until the cotton sits just short of black.

The design system inherits that logic. Everything is built from stacked value on a single hue, and the only true contrast in the room is the undyed seam thread that never went into the vat.
