Agents for dyeing keratin fibers induced by atmospheric oxygen. These agents contain at least one dye precursor for a nature-analogous dye selected from the group consisting of indole derivatives or indoline derivatives, at least one oxidation dyestuff initial product of the developer type, and at least one oxidation dye initial product of the coupler type, and do not contain ammonia or additional oxidizing agents. The dyed keratin fibers obtained by using these agents exhibit intense, long-lasting color and do not have any red, blue or purple cast.
