Abstract Color reproduction through subtractive synthesis is achieved by combining the three primary colors cyan, magenta, and yellow (CMY). Three CMY electroactive polymers are selected, synthesized, and first, integrated into monochromatic electrochromic devices (pixels) similar to electrochemical cells. In order to develop innovative trichromatic devices, new pixel architectures are proposed and compared. In particular, the stacking of the three monochromatic CMY electrochromic devices in a single system is declined in the form of three different electrochemical cells, which differ in the nature and positioning of the counter‐electrode. Overall performances are finally evaluated in terms of range and ease of assembly. The architecture with common counter‐electrode is clearly the one that offers the best potential for the development of electrochromic devices to reproduce a wide range of colors.
