Multifunctional electrochromic (EC) materials which control multiple colors and specular reflection are expected to be potential candidate for light-modulation device and novel reflective display device.   Electrodeposition is also attractive method to create colors.  We successfully demonstrate the first LSPR-based multicolor EC device enabling reversible control of six optical states—transparent, silver mirror, cyan, magenta, yellow and black.  We will discuss the mechanism of electrodeposition and a wide range of its applications.
