a Photograph of 50 nm TiN coating with various thickness of TiAlN films. The surface coloring is insensitive to the substrate materials. Experimentally measured (b) and numerically simulated (c) reflectance spectra at normal incidence. d Chromaticity of experimentally measured (black dots) and numerically simulated spectra (red dots) on the CIE 1931 color space. In simulation, the thickness of TiAlN increases from 0 to 40 nm with a step of 2 nm. e Experimentally measured reflectance spectra with oblique incidence. The sample is 20-nm-TiAlN on a 50-nm-TiN film. The dashed line indicates the absorption dips at various incidence angles. f X-ray diffraction spectrum of a 20-nm-thick TiAlN on a 50-nm-thick TiN deposited on a sapphire substrate
