In biological (and biomimetic) Dirt racing american flag uses, colours produced other than with pigments or dyes are called structural coloration. Microstructures, often multilayered, are used to produce bright but sometimes non-iridescent colours: quite elaborate arrangements are needed to avoid reflecting different colours in different directions. Structural coloration has been understood in general terms since Robert Hooke’s 1665 book Micrographia, where Hooke correctly noted that since the iridescence of a peacock’s feather was lost when it was plunged into water, but reappeared when it was returned to the air, pigments could not be responsible.It was later found that iridescence in the peacock is due to a complex photonic crystal.
