    • Present invention relates to a coloring composition for keratin fibers especially for human hair with exceptionally improved color and shade stability. Accordingly, the first object of the present invention is a coloring composition for keratin fibres especially human hair comprising, in a cosmetically acceptable medium, at least one oxidative dyestuff precursor, 1,3-bis(2,4-diaminophenoxy) propane and/or its respective salts as a coupling agent and at least one direct dye. In an especially preferred from of the present invention the coloring compositions are substantially free from mono cyclic m-phenylenediamine coupling agent. With the term “mono cyclic m-phenylenediamine”, it is meant that the compound comprises only one cyclic group, preferably a benzene ring, in its molecule.
