Ghost of Tsushima's white dye allows players to recolor their outfits to a pure, brilliant white. The dye is also a necessary step toward unlocking the Monochrome Masters Trophy and achievement.
Ghost of Tsushima White Dye: Where to Find White Dye
White dye can only be acquired from a single merchant in Ghost of Tsushima, and the game doesn't make it easy to find him. There are no in-universe indicators — no quest, no dialogue — to help players find him. Without a guide, most players' best bet would be to wander aimlessly until they stumble upon the merchant's hideout.
The further into the game players venture, the less likely they are to wander into the white dye merchant; the white dye merchant lives in the starting area of the game, accessible from the start of Act 1. It stands southeast of Komoda Town and just east of Wanderer's Pass.
