Tidal Blues and Weathered Browns
Though indigo arrives through fields or trade, coastal makers gave it maritime character using seawater dilutions and kelp ash to balance vat alkalinity. Iron from old nails or hoops modifies tannin dyes toward slate and umber, recalling pier timbers after rain. Seaweed itself is rarely a strong dyestuff, yet its ash supports chemistry, while beach-found driftwood fuels low, steady heat. Together these practices paint blues like deep channels and browns like storm-wetted rope, dependable, evocative, and grounded.
