AB - In this paper the perspectives of structural colored fibers based on photonic crystal structures are discussed. These 
fibers display the distinctive colors, which are determined by the lattice constants of the photonic crystals. The 
color-changing capability of photonic fibers with potential applications in dynamic signage and environmentally 
adaptive coloration is demonstrated. The fibers are fabricated by the silica or polystyrene colloidal particles to the 
periodically ordered interconnecting structure in a cylindrical shape. The visible light is coherently diffracted on the 
surface of the fibers, which produces a shinning color in a narrow range of wavelength. Importantly, no dyes or 
colorants are used in fabrication of such fibers, thus making the fibers resistant to color fading. This method of 
making colorful fibers could be a promising way to reduce environmental pollution in the dying industry. Additionally, 
by changing the reflective index or lattice constant of a photonic fiber, its reflected colors change proportionally to 
the shift of reflective index or lattice constant, thus enabling visually interactive and sensing textiles responsive to 
the external stimuli.
