The subject of the invention is a composition for dyeing keratin fibers, comprising: i) at least 1%, preferably at least 5%, of red henna powder (Lawsonia inermis, alba) and / or plant powder (s) indigo (s), (ii) at least one oil, (iii) optionally at least one surfactant, and (iv) water or an aqueous phase, preferably water with the understanding that ingredients (ii), (iii) and (iv) ) are pre-dispersed together to form a pre-dispersion and then mixed the ingredient (s) i) in said predispersion or said pre-dispersion is mixed with (ux) ingredient (s) i)； it also relates to a composition comprising said composition and a complement of water or aqueous phase, the method of dyeing keratinous fibers implementing said compositions, and the use of said compositions for dyeing keratinous fibers. The compositions and the poultice according to the invention make it possible to color the keratinous fibers with results of powerful coloring, chromatic, resistant to washes, perspiration, sebum and light and more durable without alteration of said fibers. In addition, the use of the compositions or the poultice does not release dust of raw materials ("dust-free"). These compositions are easy to use, safely and without risk of staining. In addition, the composition and the coloring active agent (s) remain storage stable. The treated keratin fibers have a very pleasant cosmetic, their integrity is respected.
