Nature's 'master painters': Study reveals how damselflies break optical barriers to create saturated colors

Scientists at Ben-Gurion University of the Negev (BGU) have uncovered for the first time the "ingenious" biological strategies that allow blue-tailed damselflies to produce strikingly vivid, angle-independent colors. The study, published in the Proceedings of the National Academy of Sciences, provides a new blueprint for creating sustainable, highly saturated photonic materials that could replace toxic synthetic pigments in industries ranging from cosmetics to textiles.
