According to one aspect of the present invention, a non-metal member having a colored surface is provided. The non-metal member having a colored surface includes a non-metal substrate; a metal coating layer disposed on the non-metal substrate; a light-transmissive dielectric layer disposed on the metal coating layer; and a color pattern structure disposed on the light-transmissive dielectric layer.

Non-metal member with colored surface and method of coloring non-metal surface

Provided is a coloring pattern structure. The coloring pattern structure includes: a substrate; a light-transmitting dielectric layer formed on at least one surface of the substrate; and a composite material layer disposed on an upper surface of the light-transmitting dielectric layer and formed of a metal and a first material not having a thermodynamic solid solubility in the metal, wherein the metal included in the composite material layer has a pattern coated only on portions of the upper surface of the light-transmitting dielectric layer, and the first material is coated on the remaining area where the metal is not coated.
