Beschreibung
Zusammenfassung:	A substrate treated with color development, according to the present invention is provided with areas on the surface having different temperatures to induce an average thickness difference in the coating, when a coating is formed on a matrix surface containing magnesium, thereby maintaining a metal texture unique to the substrate while enabling the development of several colors on the substrate surface with a single color development treatment, and thus can be useful in areas using magnesium materials, such as external materials for construction, vehicle interiors, and especially in the electrical and electronic parts material fields such as in mobile phone case parts.
