1. An electrochemichromic solution capable of color change when an applied potential is introduced thereto, said electrochemichromic solution comprising:

  • (a) at least one anodic compound, said anodic compound having been previously contacted with a redox agent such that said anodic compound exists in a different valence state than prior to having been contacted with said redox agent;

    (b) at least one cathodic compound; and

    (c) a solventwherein the redox potential of said anodic compound in said different valence state is greater than the redox potential of said cathodic compound while each is contacted with said solvent.
