アメリカアマガエルは、体の色を瞬時に変化させることができる。周りの温度に適応するためと、鳥などの敵の目をくらませるために自分の体の色を変えることができる。アマガエルの色を作る細胞は色素胞と呼ばれ、皮膚の層は一番上が黄色の色素の層、真ん中の透明な結晶の層、一番下が黒色の色素胞の層でできている。真ん中の層が、他の層では吸収されない緑の色を反射するので、カエルは普段緑色だが、一番下の黒い層の細胞の中で色素胞の中にあるクロマトソームという色素の粒が細胞の中央に集まっていると薄い緑色になり、細胞全体に拡散しているときは暗い緑色になる。
エアコンに頼らずに快適に建物内で生活ができるように、温度に合わせて自動的に色が変わる建物のデザインに応用できる。天候の変化の厳しい環境で着用する衣類の開発に応用できる。天気によって色を変化させる建物の外装に応用できる。
