The invention relates to the dyeing of keratin fibres using azomethine direct dyes or reduced precursors of azomethine direct dyes obtained from 5-(2-hydroxyethylamino)-2- methylphenol of formula (I) or (II). The invention relates to a dye composition comprising at least one azomethine direct dye or a reduced precursor of an azomethine direct dye, to a process for dyeing keratin fibres, using the said composition, and to their uses in the dyeing of keratin fibres. This composition allows a particularly stable and fast coloration to be obtained.
