The invention relates to a process for dyeing keratin fibres by treating said fibres with i) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, at least one of the rings of which is aromatic, ii) at least one indol(in)e compound; optionally iii) at least one metal salt, iv) at least hydrogen peroxide or at least one hydrogen peroxide-generating system and v) at least one basifying agent; to a dye composition comprising ingredients i) and ii), and optionally iii) to v) as defined previously and to a kit comprising ingredients i) to v) as defined previously. This hair dyeing process makes it possible to obtain better colorings which are more uniform, chromatic and long-lasting and which do not impair the cosmetic properties of the keratin fibres, and prevents changing of the colour associated with the presence of indol(in)e derivatives. 120.-. (canceled)21. A process for dyeing keratin fibers , comprising applying to the fibers a composition (A) comprising:i) at least one indole or indoline compound;ii) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, wherein at least one ring is aromatic; andiii) at least one metal salt chosen from transition metal salts, rare-earth metal salts, or mixtures thereof.23. The process according to claim 22 , wherein the compounds of formula (I) are monomers and Ris chosen from a hydrogen atom or an optionally substituted (C-C)alkyl radical.24. The process according to claim 22 , wherein the compounds of formula (I) are indole compounds wherein the bond between the carbon atoms bearing the radicals Rand Ris a double bond.26. The process according to claim 25 , wherein the indole compounds of formula (Ia) are chosen from 5 claim 25 ,6-dihydroxyindole claim 25 , 2-methyl-5 claim 25 ,6-dihydroxyindole claim 25 , 3-methyl-5 claim 25 ,6-dihydroxyindole claim 25 , 4-hydroxyindole claim 25 , 2 claim 25 ,3-dimethyl-5 claim 25 ,6- ...
