<p>Composition (A) comprises at least one oxidation base comprising 2-[[2-(4-amino-phenylamino)-ethyl]-(2-hydroxy-ethyl)-amino]-ethanol, and at least one coupler comprising 4-aminoindole derivatives Composition (A) comprises: at least one oxidation base comprising 2-[[2-(4-amino-phenylamino)-ethyl]-(2-hydroxy-ethyl)-amino]-ethanol (I) and its addition salts, solvates and solvates of its salts; and at least one coupler comprising 4-aminoindole derivatives of formula (II), and their addition salts, solvates and solvates of their salts. R1 : H or 1-6C alkyl group (optionally interrupted by O or NR7, and optionally substituted with OH or NR7R8); R2, R3 : H, 1-6C, preferably 1-4C alkyl (optionally substituted by one or more OH), 1-6C alkyl carboxylate, carboxyl radical, or CONR7R8; R4, R5 : H (preferred) or 1-6C alkyl; R6 : halo, 1-10C alkyl (optionally interrupted by a heteroatom comprising O or NR9 and/or optionally substituted by one or more OH or NR7R8), carboxyl radical, 1-10C alkyl carboxylate, CONR7R8, 1-10C alkoxy or 1-10C (poly)hydroxyalkoxy group, (poly)1-10C alkoxy-1-10C alkyloxy, or -O-Ak-NR9R10; Ak : 1-8C or 3-8C divalent alkylene radical (optionally interrupted by one or more oxygen atoms and/or groups NR7); R7, R8 : H or 1-8C alkyl (optionally substituted by one or more OH); either R9, R10 : 1-4C alkyl, optionally saturated; or NR9R10 : optionally saturated 5-8 membered heterocycle, one of the link can be an oxygen atom or NR11 group; and R11 : H or 1-4C alkyl (optionally substituted by one or more OH, or NR7R8). Independent claims are included for: (1) process for dyeing keratin fibers comprising applying the composition on the keratin fibers in the presence of at least one oxidizing agent for a time sufficient to develop the desired coloration; and (2) multi-compartment device in which a first compartment contains a dye composition and a second compartment contains at least one oxidizing agent.
