Dynamic color is essential for practical applications such as dynamic displays, sensors, cryptography, and camouflage. In their Communication on page 14307, Mingzhu Li et al. demonstrate a flexible, mechanically triggered color switchable sheet based on a photonic crystal-coated polydimethylsiloxane kirigami (PhC-PDMS kirigami) inspired by the structural color modulation of the male hummingbird. The PhC-PDMS kirigami shows precisely programmable structural color and keeps the color very well after recycling over 10 000 times.
