A dually tunable photonic crystal composed of thermosensitive gel particles confined in a pH‐sensitive inverse‐opal gel is reported. The position of the photonic band‐gap can be thermally regulated, while its intensity is dramatically changed by pH. Reversible, independent, and extensive switching of the position and intensity of the photonic band‐gap could be achieved using independent external stimuli.
