Novel light‐modulation materials composed of stimuli‐responsive gel particles with an added high concentration of colorants, which can modulate light due to an induced volume phase transition, have been obtained (see Figure). The light‐modulation mechanism and constitution of this material are similar to those of pigment cells existing in cephalopods, and the light absorption change is based on diffusion and aggregation of the colorants.
