Polarization related changes in color: (a) for transmission mode, from magenta to yellow in Case 1 and from cyan to magenta in Case 2. (b) For reflection mode, from green to blue in Case 1 and from red to green in Case 2. Polarization angle of incident white light (Φ) is switched for experimental results from 0° to 90°; simulation results for polarization states, which correspond to Φ varied from 0° to 90° with the step ΔΦ = 10°, are shown for comparison. Blue numbers indicate wavelengths in nm for the ideal colors.
