Color fine‐tuning of carbon nanotubes@anodic aluminum oxide (CNTs@AAO )composite thin films is achieved via isotropically etching porous AAO in phosphoric acid before CNTs growth. With the increase of etching duration from 0 to 17.5 min, the interference band with the maximum reflectance ( B max ) in visible region of the composite thin film shifts from ∼632 (salmon pink) to ∼498 nm (cyan).
