In article number 1905219, Albertus P. H. J. Schenning and co‐workers fabricate micron‐sized structural color actuators based on photonic polymer particles. The particles exhibit anisotropic spot‐like and arc‐like reflective colored domains ranging from red to blue. Upon light exposure, the particles show reversible asymmetric shape deformations combined with structural color changes. When the temperature is increased, the deformation is followed by a reduction or disappearance of the reflection.
