Coupling plasmonic silver nanocubes with a thin titania film allows three‐way tunable asymmetric color routing, in which different scattering, reflection, and transmission colors are exhibited. The color routing behavior, which is due to Fano resonances and high refractive index of titania, is changed by switching between the front and back incidence and tuning the nanocube size and titania thickness.
