Red, Green, and Blue Colors in Polymeric Electrochromics

Additive primary color-space has been completed by the discovery of the first green polymeric electrochromic. Mixing any two of the three additive primary colors (red, green, and blue (RGB)) produces thousands of colors (see Figure) resulting from the tones of polymers in different oxidation states. It is envisioned that the completion of the three components of color-space and the discovery of the first green polymeric electrochromic will herald a new polymeric electrochromic device era.
