Quasi‐amorphous colloidal structures exhibiting angle‐independent tunable photonic colors in response to the electric stimuli. Moderately polydisperse colloidal Fe 3 O 4 @SiO 2 nanoparticles dispersed in organic solvents exclusively form quasi‐amorphous photonic materials at sufficiently high concentrations, and which reversibly reflect incident light in visible region in response to the relatively low bias voltages.
