PROBLEM TO BE SOLVED: To provide a metallic material having a singular designing properties with a texture completely different for those of single substances such as metals, coating films and further chemical conversion films and to provide a method for producing it. SOLUTION: This metallic material is the one in which, as for the color tone of the surface, a dark color of <=50 index of lightness L* is used as the color of the matrix wherein a part with a light color having <=5 mm<2> average area and >=60 index of lightness L* is provided, and the surface having >=0.5μm surface roughness Ra is provided. Preferably, as for either or both of the dark color and light color, the index of color quality a* is regulated to -10 to 10, the index of color quality b* is regulated to -10 to 10, and not only material colors but also interference colors are used.
