Vial of Dye (Gray)

Gray Dye (sometimes referred to as thinner) is used to remove color added to your items using a Vial of Dye. Gray Dye can also be used as an ingredient when mixing dyes, leading to some rather strangely shaded results. See Mixing Dyes.

It is possible to use Gray Dye on armor not previously dyed, although it does not work on tattoos not previously dyed.
