Figure 8

(a) Measured reflectance spectra of colours produced with the line spacings of 4 (Hue=283), 5 (Hue=288), 6 (Hue=314), 8 (Hue=36), 10 (Hue=59) and 14 μm (Hue=60). (b) Computed reflectance spectra, each curve averaged over a few values of small NP embedding for increasing Dm (Hue). The colour scheme of the curves follows the measured/calculated Hues.
