In this study, we systematically reviewed the strategy of the tailoring intrinsic color characteristics of chromatic and achromatic metallic materials. Its scientific contribution involves defining and expanding the range of coloration of metallic materials, including single-phase solid-solution alloys and multiphase alloys that includes specific phases with chromatic colors. In chromatic single-phase alloys, the modulation of optical properties depends on the transition energy of the solid solution phase. The additional alloying elements significantly influence the optical properties, i.e., the reflectivity in the visible spectrum, by varying the transition energy of the solid solution phase. Another coloring alloy design strategy varies and realizes the intrinsic color based on the multiphase system. In particular, the microstructural design based on the multiphase forming alloy system, including the chromatic coloring phase, effectively improves the chromaticity of the alloys by blending effect from the constitutive phases. A methodological framework is subsequently suggested to realize chromatic characteristics based on the juxtaposition method. The novel alloy design method using the juxtaposition method can be considered an important strategy for developing novel coloring alloys with high chromatic color durability from achromatic metallic materials.

在这项研究中，我们系统地回顾了有色和无色金属材料的剪裁内在颜色特征的策略。它的科学贡献包括定义和扩展金属材料的着色范围，包括单相固溶体合金和多相合金，包括具有彩色的特定相。在彩色单相合金中，光学性质的调制取决于固溶相的跃迁能。额外的合金元素通过改变固溶体相的转变能量显着影响光学性质，即可见光谱中的反射率。另一种着色合金设计策略基于多相系统改变并实现本征颜色。特别是，基于多相形成合金体系的显微组织设计，包括彩色着色相，通过本构相的混合作用有效提高合金的色度。随后提出了一种方法框架来实现基于并置方法的色度特征。使用并置法的新型合金设计方法可以被认为是从消色差金属材料开发具有高色彩耐久性的新型着色合金的重要策略。
