A lamellar hydrogel with high toughness, exhibiting ternary stimuli‐responsive structural color changes has been synthesized. The gel consists of alternating hard layers of a polymeric surfactant (PDGI) and soft layers of interpenetrating networks of poly(acrylamide)–poly(acrylic acid). Reversible, wide range switching of the stop‐band position was achieved using different external stimuli of temperature, pH, and stress/strain.
