Dynamic synthesis of magnetoresponsive structural‐colored microspheres is demonstrated by combining an optofluidic approach with a magnetic property tuning method. The strategy allows for the synthesis of magnetochromatic microspheres with controlled and heterogeneous optical properties in a single synthesis environment. Orientation‐dependent color diffraction of the magnetochromatic microspheres is utilized to form structural color patterns using a patterned magnet.
