A dye composition for keratin fibres comprising, at least one direct dye to be mixed at the time of use, at a basic pH, with an oxidizing agent, and characterized in that it has a basic pH and in that it contains, as direct dye, at least one dye containing an optionally delocalizable quaternized nitrogen atom and a -Z=N- bond in which Z denotes a nitrogen atom or a -CH- radical. The use of the composition and the multi-compartment dyeing kits, for the dyeing of keratin fibres, in particular the hair and more particularly human hair, are also discussed.
