(a1) at least one organic silicon compound selected from the group consisting of silanes having one, two or three silicon atoms, and
(a2) at least one first colorant compound comprising at least one pigment based on a lamellar substrate platelet, and
applying an agent (b) to the keratinous material, wherein the agent (b) comprises:
(b 1) at least one film-forming polymer, and
(b2) at least one second colorant compound selected from the group consisting of pigments and/or direct dyes, wherein the at least one first colorant compound (a2) and the at least one second colorant compound (b2) comprise a same colorant compound or comprise different colorant compounds.
