The tuning stability of an electrically tunable photonic crystal composed of long‐range ordered crystalline colloidal arrays is significantly improved by modifying an ITO electrode with ion‐exchange resins. The thin layer of over‐coating on the ITO surface increases the number of cycles of stable color‐tuning switching from red to green to over 800 times, which is the best result ever reported for a tunable photonic crystal whose stop‐band position can be manipulated more than 100 nm.
