a Schematic representation of the vertical structure of the contraction-mode CLCE. b Top view of the contraction-mode CLCE before and after voltage application (rCLCE > rʹCLCE). c Macroscopic images showing the color of the CLCE with pre-strains of 10%, 18%, and 33%. d Reflection wavelength shift toward longer wavelengths according to the applied voltage. e, f Central wavelength (e) and central wavelength shift (f) as a function of the applied voltage. g Structural color changes at various applied voltages
