The production of structural colours concerns a large array of organisms. From bacteria (Flavobacterium strain IR1)[17] to multicellular organisms, (Hibiscus trionum,[18] Doryteuthis pealeii (squid),[19] or Chrysochroa fulgidissima (beetle)[20]), manipulation of light is not limited to rare and exotic life forms. Different organisms evolved different mechanisms to produce structural colours: multilayered cuticle in some insects[20] and plants,[21] grating like surface in plants,[18] geometrically organised cells in bacteria... all of theme stand for a source of inspiration towards the development of structurally coloured materials.
