Three-dimensional (3-D) macroporous structures with a short-range order of pore arrangements are of both scientific significance and consequent technological impact. Inspired by parrot feather barbs that display a bright blue structural color, artificial 3-D macroporous SiO₂ and TiO₂ structures were successfully fabricated by using the barbs as templates. Structural and optical characterization show that the fabricated structures are 3-D bi-continuous macroporous structures with short-range order and display bright structural colors.
