The invention relates to dyeing compositions for direct dyeing of keratinic fibres, containing, in a cosmetically acceptable medium: (a) at least one yellow or green-yellow dye corresponding to the formula (I): ##STR1## in which X=Cl, Br, F, and R.sub.1 and R.sub.2 denote, independently of each other, hydrogen, alkyl, hydroxyalkyl, or alkylaminoalkyl in which the aminoalkyl group may be mono- or disubstituted provided that R.sub.1 and R.sub.2 do not simultaneously denote a hydrogen atom, and (b) at least one blue or violet dye corresponding to the formula: ##STR2## in which R.sub.3 denotes a hydrogen atom or an alkyl, monohydroxyalkyl, polyhydroxyalkyl or alkoxyalkyl radical and R.sub.4 and R.sub.5 have separately the same meanings as R.sub.3 but cannot denote a hydrogen atom.
