Where: the groups (II)-(V) does not have more than three nitrogen atoms, and two of the three nitrogen atoms can be adjacent; the bond a of 5 membered cationic heteroaromatic group (II) is linked to N, which is linked to W 1of (I); the bond b of 6 membered cationic heteroaromatic group (III) is linked to N, which is linked to W 1of (I); the double bond c of 5 membered heteroaromatic group (IV) is linked to the N, which is linked to W 2of (I); the double bond d of 6 membered heteroaromatic group (V) is linked to the N, which is linked to W 2of (I); the bond b, linking the heteroaromatic group (III) to N, which is linked to W 1of (I), is situated in ortho position of the N carrying the group R 4, when Z 5is -CR 3-, or in para position of the N carrying the group R 4, when Z 5is C, or in ortho position of the N carrying the group R 4, when Z 5is N; or the bond c, linking the heteroaromatic group (V) to N, which is linked to W 2of (I), is situated in ortho position of the N carrying the group R 7, when Z 1 1is -CR 8-, or in para position of the N carrying the group R 7, when Z 1 1is C, or in ortho position of the N carrying the group R 7, when Z 1 1is N; and R 0, R 3, R 8, R 1 1, R 1 2, R 1 4, R 1 7, R 1 8and R 2 0are not having peroxide bond, diazo or nitroso group. Independent claims are included for: (1) a method for the simultaneous bleaching and coloring of keratin fibers, comprising mixing (A) with a solution of hydrogen peroxide in the form of paste or powder; and applying the mixture to the keratin fibers; and (2) a device with several-compartments, comprising at least two compositions, of which the compositions are mixed.
