Because all of Remnant’s T-shirts are exclusively dyed and together with the precise nature of natural dying, the reproduction of colours between orders will be unique. Prolonged exposure to sunlight will cause fading as we don’t treat our T-shirts with UV stabilizers, absorbers or blockers. Colours shown may vary from actual colours and are intended as a guide only. Remnant uses only the chemicals listed, and usually no more than three, to produce a colour. More information can be found under Material Information on each product page.
