Use of hydroxyanthraquinones for the coloration of human keratin fibres, and process and composition in which they are used. The composition contains, in a cosmetically acceptable medium, at least one hydroxyanthraquinone of the formula: in which R1, R2, R3, R4, R5, R6, R7 and R8 independently of one another denote a hydrogen atom, a hydroxyl group, an alkyl group, an alkyl group substituted, for example, by a hydroxyl, amino or acyl group, an alkoxy group, a nitro group, a halogen group, a group SO3H, CHO, CO2H or SO3Na, or a group -CO2R', in which R' denotes alkyl or an alkali metal, with the proviso that: at least two of the groups R1, R2, R3, R4, R5, R6, R7 and R8 denote hydroxyl, and that if R1 and R2 denote OH, R5, R6, R7 and R8 denoting hydrogen, then at least one of the two groups R3 and R4 is different from hydrogen, or alternatively if R1 and R3 denote OH, R2 and R4 denoting hydrogen and one or two of the substituents R5, R6, R7 and R8 denoting hydroxyl, then at least one of the substituents R5, R6, R7 and R8 is different from hydrogen, alkyl or halogen.
