A strategy for highly color‐selective polymeric photodiodes is reported. The nonabsorbing acceptor enables the color‐selective polymeric donor to fully reflect its absorption spectrum in the final quantum efficiency spectrum. The optimized planar heterojunction device structure leads to low dark current down to 1.3 nA cm −2 as well as high detectivity up to 1.15 × 10 12 cm Hz 0.5 W ‐1 .
