Abstract
In one embodiment, a chromatic device includes an active layer and an electrolyte layer in contact with the active layer, the electrolyte comprising an oxidant and a salt, wherein the active layer has a color that blocks light when metal is not in electrical contact with the active layer but changes to a translucent color that transmits light when metal is placed in electrical contact with the active layer, wherein the active layer changes color without applying electrical energy to the active layer.
