Photonic Janus particles are created by alternately sputtering silica and titania on microspheres in order to obtain a structural color gradient. In addition, the microspheres are rendered magnetoresponsive. The Janus microspheres with optical and magnetic anisotropy enable on‐demand control over orientation and structural color through manipulation of an external magnetic field, thereby being useful as active color pigments for reflection‐mode displays.
