This color-treated base material, which comprises a matrix comprising magnesium, a film formed on the matrix and containing a compound represented by chemical formula 1, and a wavelength conversion layer formed on the film, can improve the durability of the base material while maintaining the unique metal texture and gloss of the base material and can uniformly realize various colors, such as blue and green, including an achromatic color such as black, on the surface of the base material and thus can be usefully used in the fields of building exterior materials, automobile interiors, and particularly electrical/electronic component materials, such as mobile product frames, in which a metal material is used. |
