The invention relates to an agent for colouring fibres (A) which is produced by mixing two components (A1) and (A2) and is characterised in that the component (A1) contains at least one compound of formula (I), wherein X represents a halogen atom, a methoxy group or an ethoxy group; Y represents an oxygen atom, a sulphuric atom or a selenium atom; and R1 and R2 can be identical or different and represent independently from each other hydrogen, a halogen atom, an (C1-C4) alkyl group, an (C1-C4) alkyl group substituted by a halogen atom, an (C1-C4) alkoxy group, a nitro group, an acetamido group or a NraRb group, whereby the radicals Ra and Rb can be identical or different and represent independently from each other hydrogen, an (C1-C4) alkyl group, an optionally substituted carbocycle or an (C1-C4) alkane carbonyl group, or Ra and Rb form, together with the nitrogen atom, a heterocyclic (C3-C6) group; and the component (A2) contains at least one compound from the group comprising amines, aminonitrobenzenes and phenoles. The invention also relates to a method for colouring hair by using said agent and a multiple component kit.
