Abstract: A multilayer coating that provides a switchable color includes a substrate, an electrically conductive heating paint layer disposed over the substrate, a non-electrically conductive paint layer disposed over the electrically conductive heating paint layer, and a thermochromic paint layer disposed over the non-electrically conductive paint layer. The non-electrically conductive paint layer has a base color at 25° C. The thermochromic paint layer has a first preset color at 25° C. and a second preset color at a switching temperature that is higher than 25° C. Characteristically, the first preset color is matched to the base color. A controllable voltage source is in communication with the electrically conductive heating paint layer to switch between a first preset color and a second preset color.
