In this work, hollow polydopamine (PDA) amorphous colloidal structures with liquid-immune and angle-independent structural colors have been successfully fabricated. Owing to the high refractive index contrast derived from PDA, its light-absorbing nature, as-prepared materials demonstrate brilliant even in liquid environments.
