a The simulated reflection spectra of different metasurfaces. The scaling parameter of from top to bottom are S = 0.80, 0.85, 0.95, 1.00, 1.05, 1.10, and 1.20. All the other parameters are the same Fig. 1. b The corresponding colour coordinates in CIE 1931 chromaticity diagram. The dashed triangle represents Rec. 2020 for UHDTV. c Unit cell of metasurface with size deviation Δr introduced to the central nanopillar. d Numerically calculated reflection spectra as a function of Δr.
