Scope note
Aromatic, dark brown liquid prepared from the aqueous extract of the seeds of several species of the genus Coffea, particularly C. arabica. Coffee is used as a beverage and as a brown dye. On wool, it produces a dark yellow-tan color with a chrome mordant and a tan with an aluminum mordant. Both colors have fair light fastness. Coffee colors on cotton are not fast. Some restorers have used coffee to tint bleached papers or repair regions to a shade that corresponds to surrounding areas.
