A highly flexible and durable light modulator consisting entirely of polymer‐gel materials was fabricated. In this light modulator, colored gel particles responsive to stimuli are dispersed and fixed in a second stimuli‐non‐responsive gel matrix (“gel‐in‐gel” system), analogous to the skin of a cephalopod. The flexible light modulator exhibits a dramatic change in color as the colored gel particles change volume in response to temperature changes (see Figure).
