Abstract

Accurate measurements of the optical properties of metal surfaces responsible for their colors can be made in mathematical terms by using an automatic recording spectrophotometer. A freshly prepared surface of MgO having a reflectance of the order of 0.98 which varies only slightly over the whole spectrum is used as a standard, and carefully polished flat metal surfaces make up the specimen. All metals have an absorption band. This band is associated with the energy required to remove an electron from a state in the d shell to an empty state in the s shell. The wavelength of this absorption band governs the color characteristics of metal surface.
