a Theoretical (black rhomboid) and experimental (blue rhomboid) chromaticity gamut of samples A and B illustrated in the SEM images of panel (b). The corresponding colours for different input polarization angles Δϕ are shown in panel (a). c FDTD-calculated theoretical transmission (T) response (dashed line) compared to experimental measurements (solid line)
