How the Eurasian jay expands its color palette by optimizing multiple scattering Ghent University
The production of structural color in nature is still incompletely understood. Multiple scattering exerts critical effects on synthetic disordered systems, but its effects on structural colors in natural materials are not yet well known. Here, electron microscopy, optical modeling, and biomimicry are used to show that variation in the thickness of the feather nanostructures creates periodic color variations in Eurasian jay wing covert feathers, ...
