The decorated article, for instance an instrument dial or watch dial, article of jewelry or ornamented article of use, possesses at least one surface or decorative layer which, in the presence of reflected light, appears to be colored, for instance yellow, red, blue or gray. This surface or decorative layer is formed by a silicon substrate or substratum, or lower layer as well as an upper or top layer fixedly connected thereto, for instance, connected by a reaction and/or deposition with the substratum. This top layer is permeable for optical light and comprises a silicon compound, preferably silicon dioxide, which under standard conditions is solid and practically inert, and has a thickness sufficient for interference-color formation, typically in the range of 50-1000 nm, preferably 90-500 nm. The surface or decorative layer can constitute the decorated article itself, for instance an instrument dial or watch dial or can be part of a decorated article, for instance a cigarette lighter.
