A porous gel exhibiting angle‐independent structural color was obtained by a facile self‐assembly approach. The porous swollen gel changes color reversibly in response to changes in solvent composition and temperature as a result of changes in the wavelength dispersions of the refractive indices of the gel portion and the solvent portion in the pores.
