A simple and rapid method for micropatterning multiple types of photonic colloidal crystals exhibiting structural colors with low‐angle dependency on a single microfluidic sheet is described. Colloidal particles are sequentially introduced and crystalized inside the hemispherical dome‐top polydimetylsiloxane microchannels. This patterning method can be effective to realize an optical filter for full‐color and wide‐viewing‐angle reflective displays.
