Yamabuki, ukon, kariyasu — luminous yellows from mustard to pale gold.
Japanese yellow is a botanical record. Yamabuki names a flowering shrub. Kariyasu is the dye-grass that produces it. Ukon is turmeric. Kuchinashi is gardenia fruit. Each pigment carries its plant's name — meaning these yellows aren't abstractions but recipes, each tied to a specific season, soil, and dye process.
