The Black Dye Tub is a 1-year veteran reward that allows special colored dying of the jet black color. Ultima Online's black dye tub remains the one and only way to dye things jet black in color. This dye tub can be used by anyone after being claimed in the veteran rewards. This coloring is considered rare among most players in Ultima Online. Interestingly enough black dye was first introduced to Ultima Online by hackers!
