  The present invention relates to a composition for dyeing keratin fibres, comprising at least one cationic diazo direct dye chosen from the compounds of formula (I) or (II) below, the mesomeric forms thereof, and also the acid-addition salts thereof and solvates thereof. The invention allows the production of colorations that are resistant to the various attacking factors to which the hair may be subjected, especially to shampooing. The invention also makes it possible to obtain blue or violet colorations, especially sparingly chromatic blue colorations, which lead to fundamental and/or natural shades. Moreover, the direct dyes used in the context of the invention are light-stable and stable under standard lightening dyeing conditions, in particular in the presence of an oxidizing agent and/or of ammonia.
