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 4when 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 of coloring keratin fibers, particularly human keratin fibers, comprising: either applying (A) to the fiber for a sufficient time to develop the desired coloration, rinsing and optionally shampooing, rinsing again and drying; or applying (A) to the fiber for a sufficient time to develop the desired coloration without final rinsing; or storing a composition (A1) comprising (I) in separated form, and composition (B1) comprising one or more oxidizing agent; optionally a composition (C1) in a medium; and then mixing (A1)-(C1) at the time of use before applying the mixture on the keratin fibers, where (A1) or (C1) comprises one or more para-aminophenol oxidation base, and nitrogenated non-heterocyclic coupler; and (2) a device with several-compartment or kit with several compartments, comprising a first compartment containing composition (A1); a second compartment containing the composition (B1); and optionally third compartment containing composition (C1).
