Color-filtered images corresponding with Fig. 3A and B. The color dispersion of LH and RH reflected light was imaged by inserting a tunable liquid crystal filter in front of the CCD camera. Ten-nanometer-wide reflection bands were imaged at (A and B) 430 nm, (C and D) 530 nm, and (E and F) 630 nm. Images with different colors were individually normalized (images with the same color have the same normalization).
