A new light‐driven chiral molecular switch doped in a stable blue phase (BP) liquid crystal allows wide optical tunability of three‐dimensional cubic nanostructures with a selective reflection wavelength that is reversibly tuned through the visible region. Moreover, unprecedented reversible light‐directed red, green, and blue reflections of the self‐organized three‐dimensional cubic nanostructure in a single film are demonstrated for the first time. Additionally, unusual isothermal photo‐stimulated less ordered BP II to more ordered BP I phase transition was observed in the system.
