The first localized surface plasmon resonance (LSPR)‐based multicolor electrochromic device with five reversible optical states is demonstrated. In this device, the size of deposited silver nanoparticles is electrochemically controlled by using a voltage‐step method in which two different voltages are applied successively. The electrochemically size‐controlled silver nanoparticles enable a reversible multiple‐color change by a shift of the LSPR band.
