Mixed silver and gold plasmonic nanoparticle architectures are synthesized using DNA‐programmable assembly, unveiling exquisitely tunable optical properties that are predicted and explained both by effective thin‐film models and explicit electrodynamic simulations. These data demonstrate that the manner and ratio with which multiple metallic components are arranged can greatly alter optical properties, including tunable color and asymmetric reflectivity behavior of relevance for thin‐film applications.
