The invention relates to the dyeing of keratin materials using diketopyrrolo [3, 4-c] pyrrole thiol and disulfide dyes. The invention relates to a dye composition comprising a diketopyrrolo [3, 4-c] pyrrole chromophore thiol or disulfide dye and to a dyeing process with a lightening effect on keratin materials, in particular keratin fibers, especially human keratin fibers, such as the hair, using said composition. It similarly relates to novel diketopyrrolo [ 3, 4-c] pyrrole chromophore thiol dyes and to the uses thereof in lightening keratin materials. This composition makes it possible to obtain a coloring with a lightening effect which is particularly resistant and visible on dark keratin fibers.
