A method of manufacturing an article having a system of interference filters comprising two interference filters (10, 20) on the article, each for providing a visible color shifting effect when tilted between first and second viewing angles in the presence of incident light, comprising: (a) identifying layer materials and layer thicknesses for a design of a first interference filter comprising two first metal layers (12, 16) and a first spacer layer therebetween, and for a design of a second interference filter comprising two second metal layers (22, 26) and a second spacer layer therebetween, wherein the layer materials and layer thicknesses are such that an optical thickness of the first spacer layer is different from an optical thickness of the second spacer layer, and wherein the first and second interference filters match in hue at the first viewing angle, and the first and second interference filters mismatch in hue at the second viewing angle; wherein the difference in hue is less than ten degrees when the first and second interference filters match in hue at the first viewing angle, and wherein the difference in hue is greater than ten degrees when the first and second interference filters mismatch in hue at the second viewing angle; (b) modifying the design of the first interference filter or the design of the second interference filter so as to obtain designs of first and second modified interference filters, comprising modifying the layer material or the layer thickness of one of the first metal layers (12, 16) or of one of the second metal layers (22, 26), or modifying the first or second spacer layers (14, 24) by including an absorber layer therewithin, wherein a difference in lightness at the first viewing angle between the first and second modified interference filters is less than a difference in lightness at the first viewing angle between the first and second non-modified filters; and wherein the first and second interference filters continue to match in hue at the first viewing angle after modifying the design of the first interference filter or the design of the second interference filter; and (c) providing a system comprising two interference filters (10, 20) according to the designs of the first and second modified interference filters on the article. (a) identifying layer materials and layer thicknesses for a design of a first interference filter comprising two first metal layers (12, 16) and a first spacer layer therebetween, and for a design of a second interference filter comprising two second metal layers (22, 26) and a second spacer layer therebetween, wherein the layer materials and layer thicknesses are such that an optical thickness of the first spacer layer is different from an optical thickness of the second spacer layer, and wherein the first and second interference filters match in hue at the first viewing angle, and the first and second interference filters mismatch in hue at the second viewing angle; wherein the difference in hue is less than ten degrees when the first and second interference filters match in hue at the first viewing angle, and wherein the difference in hue is greater than ten degrees when the first and second interference filters mismatch in hue at the second viewing angle; (b) modifying the design of the first interference filter or the design of the second interference filter so as to obtain designs of first and second modified interference filters, comprising modifying the layer material or the layer thickness of one of the first metal layers (12, 16) or of one of the second metal layers (22, 26), or modifying the first or second spacer layers (14, 24) by including an absorber layer therewithin, wherein a difference in lightness at the first viewing angle between the first and second modified interference filters is less than a difference in lightness at the first viewing angle between the first and second non-modified filters; and wherein the first and second interference filters continue to match in hue at the first viewing angle after modifying the design of the first interference filter or the design of the second interference filter; and (c) providing a system comprising two interference filters (10, 20) according to the designs of the first and second modified interference filters on the article.
