Unique blue fruit’s colour does not fade even after a
century
The ‘brightest’ thing in nature, the Pollia condensata
fruit, does not get its blue colour from pigment but instead uses structural
colour – a method of reflecting light of particular wavelengths- new research
reveals. The study was published today in the journal PNAS.
Most colours around us are the result of pigments. However, a few examples in nature – including
the peacock, the scarab beetle and now the Pollia condensata fruit – use
structural colour as well.
