Composition (A) comprises: (a) at least one cationic surfactant having ammonium salt structure (I)； (b) at least one oxidizing agent； and (c) at least one dye comprising oxidation dye precursors, direct dyes, and/or at least one alkaline agent. Composition (A) comprises: (a) at least one cationic surfactant having ammonium salt structure of formula (R3-CH(OH)-CH 2-N +>；(-[R2] p)-[-CH 2-CH(OH)-R1] n(X ->；)) (I)； (b) at least one oxidizing agent； and (c) at least one dye comprising oxidation dye precursors, direct dyes, and/or at least one alkaline agent. R1 : H, linear 1-6C or branched 3-6C alkyl, optionally carrying at least one hydroxyl group, or alkoxy group, where alkyl moiety is 4C alkyl； R2 : linear 1-6C or branched 3-6C alkyl group； R3 : 8-32C hydrocarbon group (optionally saturated and comprising one or more (non)conjugated unsaturations, optionally carrying at least one OH), or -CH 2-O-R3a； R3a : 8-32C hydrocarbon (saturated and comprising one or more (non)conjugated unsaturations optionally carrying at least one OH)； n : 1-3； p : 0-2, where the sum of n and p is 3； and X ->； : counter ion. An independent claim is included for multi-compartment device comprising: a first compartment containing a composition comprising at least one dye comprising oxidation dye precursors, and/or direct dyes, and/or at least one alkaline agent； and a second compartment containing a composition comprising one or more oxidizing agents, at least one of two compositions comprising at least one cationic surfactant (I), dyes, alkaline agent, oxidizing agents, or cationic surfactant (I).L'invention a pour objet une composition comprenant : (a) au moins un tensioactif cationique de formule suivante (I) : où : R , identiques ou non, représentent un hydrogène, un alkyle en C -C , éventuellement porteur d'au moins un hydroxyle, alcoxy ； R , identiques ou non, représentent un alkyle en C -C ； R représentant un radical hydrocarboné en C -C , linéaire ou ramifié, saturé ou non, éventu
