vat color
Noun: A type of dye, insoluble in water, that is applied to a material (especially cotton) through a chemical process. This process involves first reducing the dye to a soluble, alkaline form so it can penetrate the fibers. After application, the original insoluble dye is regenerated inside the material by oxidation, resulting in a colorfast finish.
