A method of preparing a multilayer coating system onto an optionally pre-coated substrate comprising at least steps and or at least steps , and , namely applying a pigmented basecoat composition to an optionally pre-coated substrate and forming a first coating film on the optionally pre-coated substrate, wherein the basecoat composition comprises at least one organic black pigment, optionally applying a second pigmented basecoat composition different from the basecoat composition applied in step to the first coating film present on the substrate obtained after step and forming a second coating film adjacent to the first coating film, and applying a coating composition different from the composition applied in step and in optional step to the first coating film present on the substrate obtained after step and forming a second coating film adjacent to the first coating film in case optional step is not performed, wherein the coating composition is a pigmented topcoat composition, or applying a coating composition different from the composition applied in step and in optional step to the second coating film present on the substrate obtained after step and forming a third coating film adjacent to the second coating film in case optional step is performed, wherein the coating composition is a clearcoat composition, wherein the second coating film obtained after step or the third coating film obtained after step is the outermost film of the formed multilayer coating system, characterized in that neither the second basecoat composition applied in optional step nor the coating composition applied in step or comprises any black pigments, and in that - in case steps , and are performed - the second basecoat composition or - in case steps and are performed - the topcoat composition comprises at least one non-black coloring pigment having a volume average particle size of <1000 nm in an amount in the range of from 0.01 to 7.50 wt.-%, based in each case on the total solid content of the respective composition, wherein said at least one non-black coloring pigment is in each case incorporated into the respective composition in the form of a pigment paste. applying a pigmented basecoat composition to an optionally pre-coated substrate and forming a first coating film on the optionally pre-coated substrate, wherein the basecoat composition comprises at least one organic black pigment, optionally applying a second pigmented basecoat composition different from the basecoat composition applied in step to the first coating film present on the substrate obtained after step and forming a second coating film adjacent to the first coating film, and applying a coating composition different from the composition applied in step and in optional step to the first coating film present on the substrate obtained after step and forming a second coating film adjacent to the first coating film in case optional step is not performed, wherein the coating composition is a pigmented topcoat composition, or applying a coating composition different from the composition applied in step and in optional step to the second coating film present on the substrate obtained after step and forming a third coating film adjacent to the second coating film in case optional step is performed, wherein the coating composition is a clearcoat composition, wherein the second coating film obtained after step or the third coating film obtained after step is the outermost film of the formed multilayer coating system, <EOS>
