Experimental evidence and published results show that when dyes are faded they are usually oxidised, probably by atmospheric oxygen. In certain systems reduction may occur, e.g. when the substrate is more readily oxidised than the dye or under anaerobic conditions in the presence of a hydrogen donor.
