Abstract: An exemplary embodiment relates to a nano-color coating layer and a method of forming the same, and more particularly, to a color structure representing a back side-reflection color with metallic luster and high chroma when observed in a substrate incident mode by greatly enhancing light absorbance at a specific wavelength using a resonance structure in which a light absorbing material is inserted between a transparent substrate and an upper mirror layer. In addition, the exemplary embodiment provides a color structure which controls metallic luster and texture of a high-chroma color from gloss-semi-gloss-matte texture in various ways by introducing a haze surface structure in which light scattering occurs on at least one surface of the transparent substrate.
