Figure 8. The measured angle-resolved reflectance spectra from the fabricated green color scales with totally 15 layers (Green_3) under normal incidence (a) and oblique incidence (c), respectively.

The detection angle changes from 0° to ±40° progressively. For comparison, the same measurements were repeated on PMMA grating (b,d). Detailed descriptions are given in the text.
