Abstract

In this paper, color specification procedure for structural colors by using reflection spectrum in visible wavelength is proposed. The tristimulus values in XYZ color system are obtained from the reflection spectrum calculated by transmission-line theory, and transformed into tristimulus values in standard red-green-blue (sRGB) color system. By using the sRGB, structural color is quantitatively specified. From some numerical results, it is shown that our suggested color specification procedure is valid.
