This presentation will introduce a powerful colloidal co-assembly approach that results in large-scale, highly ordered porous photonic crystals. The unique coloration of these opal films combines iridescence with plasmonic effects. Their composition and optical properties are demonstrated to be locally tunable using selective functionalization of the doped opals. The latter exhibit a sharply defined threshold wettability for infiltration. This liquid-specific wetting behavior naturally couples to macroscopic color changes.
