Hierarchical dome patterns are prepared via a novel single‐step patterning process. Photonic domes with isotropic reflection colors are patterned on a prepatterned glass substrate with a hydrophobic moiety using photocurable emulsion droplets of all‐equal size, which contain concentrated silica particles. Furthermore, embossed domes are patterned with PS particle‐stabilized photocurable emulsion droplets, which can act as a near‐field microlens array.
