a (i) Schematic design of tandem nanodisk array. Measured (ii) reflective and (iii) transmissive color images corresponding to (i) with radii 35 ≤ R ≤ 110 nm and periods 250 ≤ P ≤ 450 nm. Scale bar: 40 µm. b Schematics of a plasmonic stereoscopic printing device with dependence on polarization. c Optical color palettes for elliptical pixels varied by Lx and Ly, polarized along (i) y and (ii) x direction. d Optical color palettes for coupled nanosquare pixels at combinations of w and g, polarized along (i) x and (ii) y direction
