<p>Composition for dyeing of keratinous fibers comprises a primary oxidation base comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one (I) and its salts, a secondary oxidation base comprising para-phenylene diamines, a coupler comprising meta-aminophenols and an oxidizing agent. The pH of the composition is 5.5-7.5. Composition for dyeing of keratinous fibers comprises a primary oxidation base comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one of formula (I) and its salts, a secondary oxidation base comprising para-phenylene diamines, a coupler comprising meta-aminophenols and an oxidizing agent. The pH of the composition is 5.5-7.5. Independent claims are included for: (1) dyeing of keratinous fibers comprising application of the dyeing composition on the keratinous fibers and rinsing, optionally washing with shampoo, rinsing again and drying; and (2) a device with compartments comprising a first compartment containing a composition (A1) comprising a primary oxidation base comprising 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one (I) and its salts, a secondary oxidation base comprising para-phenylene diamines, a coupler comprising meta-aminophenols and an oxidizing agent and a composition (A2) comprising an oxidizing agent in a medium.
