• Controllable structural color
• Colloidal magnetically assembled photonic crystal
• Miniemulsion polymerization

A facile, convenient and flexible method to tune the structural color of the colloidal magnetically assembled photonic crystals(CMA-PCs) was proposed. The mechanism to tune structural color could be attributed to the significant influence of the surfactant sodium dodecyl sulfate(SDS) concentration on the particle size, especially on the magnetite content of the superparamagnetic composite nanoparticles(MCNPs). By adjusting SDS concentration in miniemulsion polymerization of MCNPs, CMA-PCs-with desired diffraction colors could be obtained.
