A new multicolor electrochromic (EC) device based on Ag nanoparticle aggregation and decentralization is demonstrated. Color states that can reversibly be changed from transparent to yellow, pink, purple‐violet, and dark blue under a constant direct‐current field are obtained. Moreover, these color states remain after removing the electric field. A novel EC cell with eight indium tin oxide electrodes is fabricated to enhance the repeatability and stability of the system.
