Abstract
A method of producing a color change in a distinct element of solid, insoluble color changing material capable of reversibly changing color by reaction with soluble reactants. Reactants at a point spaced apart from the distinct element are electrochemically generated, diffuse through an electrolyte, and react with the distinct element to cause a reversible color change.
