## Abstract A reversible color change of a polyaniline‐infiltrated TiO~2~ inverse opal photonic crystal (PC) film can be obtained when the PC is switched from an acidic to alkali vapor environment. In a saturated NH~3~ environment, the stopband of the as‐prepared PCs changes from 556 to 688 nm; suc
