structural color
struc·tur·al col·or
a color created by an optic effect (for example, through interference, refraction, or diffraction). Many naturally occurring blues fall in this class. Compare: natural pigment.

* Cypris (US)--chemical technology to deliver the phenomenon of structural color
This iridescent effect is due to "structural color," by which an object generates color simply due to the way light interacts with its geometric structure.
The structural color was maintained during quaternization.
Nature often uses shapes rather than pigments to produce color, such as the feathers of a peacock, which is considered a structural color. There are so many good examples, such as self-healing and self-assembly found in pearl shells or plants' color changes to resist the harmful UV radiation and nutrient distribution methods, not to mention shape memory or self-stratifying properties.
This kind of pigmentation is referred to as "structural color."

The author has organized the main body of her text in nine chapters devoted to an introduction to bioinspired photonic systems, low dimensional structural color, complex structural color, and a wide variety of other related subjects.
The film was reported to exhibit structural color changes when elongated in the horizontal direction due to reduction of the sphere spacing in the longitudinal direction [14].
In contrast to the pigments and dyes, the called structural color is based on the interaction between light and the structures rather than the material properties.
He explains in the preface: "To understand the nonequilibrium order formation as a whole...one should intuitively feel and actually touch the phenomena, and then understand how they are analyzed from a scientific viewpoint." Six contributed chapters provide an introduction and discuss the Belousov-Zhabotinsky reaction, dynamics of droplets, density oscillators, colloidal crystals, and basic observations and analysis of structural color in nature.
The blue is a structural color, which means that reflected light shines off the feathers.
Now, researchers at the University of Michigan have found a way to lock in so-called structural color, which is made with texture rather than chemicals.
