Abstract
The present invention relates to a composition for the coloring of keratin fibres, notably hair, that comprises a phenoxazinone dye of formula (I) as well as the use of this dye for hair coloring. The invention thus makes it possible to obtain coloration that respects the nature of the hair and offers strong shades, which are resistant and have low selectivity.
