ABSTRACT:
A desired color shade is produced on a textile substrate by treating a dyed textile substrate, which has an initial color shade which is partly due to color caused by the presence thereon of a vat dye and partly due to color caused by the presence thereon of a sulfur dye, with a chlorine-free decolorizing agent, such as hydrogen peroxide in an aqueous alkaline medium, whereby the color shade of the substrate is changed from said initial color shade to said desired color shade by removal therefrom of a proportion of the color attributable to the sulfur dye without removing as large a proportion of the color attributable to the vat dye.
