A system comprising: b) at least one first colour layer containing a dye and/or pigment, c) on the at least one first colour layer an effect layer containing at least one platelet-shaped effect pigment, wherein the at least one platelet-shaped effect pigment is composed of particles having an average length of 2 to 500 μm, an average width of 2 to 500 μm and an average thickness of at most 1 μm, and d) on the effect layer at least one second colour layer containing a dye and/or pigment, wherein each of the at least one first colour layer and of the at least one second colour layer contains a dye (26, 30) and/or pigment being no platelet-shaped effect pigment, wherein the at least one dye and/or at least one pigment included in the at least one first colour layer is different from the at least one dye and/or at least one pigment included in the at least one second colour layer, and wherein, at least if the at least one first colour layer has a sum of reflectance and scattering of less than 40%, the system further comprises: a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%, wherein the system does not contain any interference pigment, wherein an interference pigment is defined to be a pigment which produces an interference of light waves. b) at least one first colour layer containing a dye and/or pigment, c) on the at least one first colour layer an effect layer containing at least one platelet-shaped effect pigment, wherein the at least one platelet-shaped effect pigment is composed of particles having an average length of 2 to 500 μm, an average width of 2 to 500 μm and an average thickness of at most 1 μm, and d) on the effect layer at least one second colour layer containing a dye and/or pigment, wherein each of the at least one first colour layer and of the at least one second colour layer contains a dye (26, 30) and/or pigment being no platelet-shaped effect pigment, wherein the at least one dye and/or at least one pigment included in the at least one first colour layer is different from the at least one dye and/or at least one pigment included in the at least one second colour layer, and wherein, at least if the at least one first colour layer has a sum of reflectance and scattering of less than 40%, the system further comprises: a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%, wherein the system does not contain any interference pigment, wherein an interference pigment is defined to be a pigment which produces an interference of light waves. wherein each of the at least one first colour layer and of the at least one second colour layer contains a dye (26, 30) and/or pigment being no platelet-shaped effect pigment, wherein the at least one dye and/or at least one pigment included in the at least one first colour layer is different from the at least one dye and/or at least one pigment included in the at least one second colour layer, and wherein, at least if the at least one first colour layer has a sum of reflectance and scattering of less than 40%, the system further comprises: a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%, a) below the at least one first colour layer a lower layer containing a pigment and having a sum of reflectance and scattering of at least 40%, wherein the system does not contain any interference pigment, wherein an interference pigment is defined to be a pigment which produces an interference of light waves.
