Abstract: In one embodiment, a chromatic device includes a transparent conductive substrate, an active layer provided on the conductive substrate, the active layer comprising a conducting polymer, an electrolyte layer in contact with the conductive substrate and the active layer, the electrolyte comprising an oxidant and a salt but not comprising an acid, and a metal element configured to be selectively placed in and out of direct electrical contact with the conductive substrate or the active layer, wherein the active layer has a color that blocks light when the metal element is not in electrical contact with the conductive substrate but changes to a translucent color that transmits light when the metal element is placed in electrical contact with the conductive substrate or the active layer, wherein the active layer changes color without applying external energy to the active layer.
