Abstract: Described herein are photonic crystals comprising a plurality of substantially uniform zein particles. The photonic crystals can be fabricated by assembling the plurality of substantially uniform zein particles into one or more ordered and periodic structures that generate structural color. Also described herein are methods of using the photonic crystals described herein, e.g., as colorants in consumer products, such as food, drugs and/or cosmetics.
