Abstract: Many living organisms have evolved hard photonic structures to 
produce colouration by light interference, as a result of a continuing 
natural selection that started million years ago. The physical origin of 
the spectral selective behaviour of this kind of structures - which only 
uses moderate refractive indexes - will be reviewed. Many examples from 
recent studies will be given, showing that one-, two- and 
three-dimensional photonic crystals with partial gaps are active in 
nature. The possible biomimetic transposition of these natural structure 
to actual artificial devices will also be briefly discussed.
