The color-change of splat cooled Ag-(40∼60)at%Zn alloy foils were studied by using chromametry, spectral reflectivity measurements and X-ray diffractometry. When the foil is quenched from 623 K and annealed in 473 K, it shows pink and silver colors, respectively. They locate between 5YR and 5R on CIE(1931) chromaticity diagram. The X-ray diffraction patterns imply that the pink and silver colors correspond to the β′ and ζ phases, respectively. At Ag-50 at%Zn, the color-change temperatures from pink to silver and from silver to pink are equal to 425 and 553 K, which correspond to the β′→ζ and ζ→β transition temperatures, respectively, and which show the composition dependence. The spectral reflectivity of pink color shows a characteristic absorption at the wavelength of 530 nm associated with the interband transition of electrons on the Fermi surface, whereas that of silver color shows no absorption. The color-change is determined by the difference of electronic structures of both phases.
