Tinctorial composition (A) (for dyeing keratinous fibers in human), comprises a mixed dye (I) comprising two different chromophores, where at least one of the chromophores is a chromophore of tri (hetero) aryl methane family bonded by an intermediate of a linking bond stopping the delocalization of electrons in chromophores in the medium. Independent claims are also included for: (1) a process of coloring keratinous fibers, in human, comprising applying a composition (A) on optionally dried fibers, optionally in the presence of an oxidizing agent, allowing (A) to be retained to obtain the desired coloration, rinsing the fibers optionally, washing the fibers and rinsing, and drying or allowing the fibers to dry; (2) a device with several compartments, where one compartment comprising (A) and an optional additional direct dye, optionally an oxidation base, optionally a coupler, and another compartment comprising an oxidizing agent; and (3) a mixed dye (I).
