When LK is linked to W' 5 it can be terminated by a heteroatom or group comprising a heteroatom preferably N or O. When it is linked to W 6 it can be terminated by a group comprising a heteroatom -CO- or -SO 2-. When LK is linked to W 3 the link is via a carbon atom. The electroneutrality of the compounds is ensured by one or more cosmetically acceptable anions. Independent claims are included for: (1) A dye composition comprising as a direct colorant at least one of the claimed compounds; (2) a method of coloring keratinic fibers by contacting them with the claimed composition for a sufficient time to attain the desired effect; (3) a kit comprising in one compartment the claimed composition and in another an oxidant compound.
