1. A hair coloring composition, comprising a medium and at least one aromatic dye in the medium, the composition optionally further comprising pigment microparticles, wherein the aromatic dye is selected from a member of the aromatic dye group consisting of a rylene dye, a nitro dye, an aryl azo dye, a heteroaryl azo dye, a chinon dye, a chinonimine dye, a chinondiimine dye, a methin dye, an azomethine hydrazone dye, an azomethine imine dye, and a porphyrin dye, wherein the selected member of the aromatic dye group optionally is substituted with one or more hydrophobic moieties having a linear or non-linear structure, and wherein the selected member of the aromatic dye group is substituted with a reactive moiety R20,
wherein the reactive moiety R20 is selected from (C0-C6 alkyl)OH, (C0-C6 alkyl)NH2, (C0-C6 alkyl)Cl, (C0-C6 alkyl)Br, (C0-C6 alkyl)I, (C0-C6 alkyl)OSO2(C0-C3 alkyl), (C0-C6 alkyl)OSO2(aryl), (C0-C6 alkyl)SO2C1, (C0-C6 alkyl)Si(O—(C1-C3 alkyl))3, (aryl)SO2C1, aryl(C0-C4)OH, aryl(C0-C4)NH2, wherein the aryl is a C5-C10 aryl, wherein 1 or 2 of the carbon atoms of the C5-C10 aryl may be replaced by N, O or S, and wherein the C5-C10 aryl optionally is substituted with up to 3 substituents selected from the group consisting of halogen, C1-C6 alkyl, C1-C6 alkoxy, -NH(C1-C6 alkyl), —N(C1-C6 alkyl)2, and formula (30),
