As the cathode reduction component,;Wherein R 21 and R 22 are independently selected from the group consisting of an alkyl group having 1 to 10 carbon atoms, a phenyl group substituted with a group selected from the group consisting of Cl, Br, cyano, an alkyl group having 1 to 4 carbon atoms, and Cl, Br, A benzyl group substituted with a group selected from the group consisting of 1 to 4 alkyl groups, and R 31 is an alkyl group having 1 to 10 carbon atoms.) Dimethylphenazine as an anodizing component, propyl carbonate as a solvent and / or gamma -Butyrolactone can exhibit an orange color of yellow or a combination color of red and yellow depending on the change in the intensity of a voltage applied in accordance with the mixture concentration ratio of the red cathodic reducing material and the yellow anodic oxide material Electrochromic composition.
