A colored article, e.g., a multicolored filter for a display device, comprises a first electroconductive layer with a low resistance formed on a substrate. A second electroconductive layer resistant to electrolytic corrosion and comprised, e.g., of SnO.sub.2, Sb.sub.2 O.sub.3, ZnO, CdO, Ga.sub.2 O.sub.3, Au, Ag, Ni, Al and Si, is formed directly on the first layer. A color layer is formed on the second layer by electrodeposition to impart a desired color tone to the article.
