This study introduces a versatile method for modifying the optical properties of plasmonic substrates by inkjet printing of commercially available, transparent inks with various refractive indices. The large‐scale and cost‐efficient process is demonstrated on tilted aluminum nanolamellas. They show vivid and bright colors based on a Fano resonance, which is highly susceptible to the surrounding material. Furthermore, color rendering can be made strongly angle‐dependent and asymmetric, which is in contrast to the nonvariable color generation enabled by conventional inkjet printing.
