a Three-dimensional schematic of the FP cavity, with the top-layer PPD-printed thin film thickness t and dielectric spacer thickness d as variables. b Reflectance spectra with variable t and fixed d = 200 nm. c 1931 CIE color coordinates corresponding to (b). d Reflectance spectra for variable d and fixed t = 15 nm. e CIE color coordinates corresponding to (d). f The color palettes are based on the simulated reflectance spectra with varying d and t.
