SCARAB BEETLE DIFFRACTION GRATINGS. "A diffraction grating is any nanoscale array of parallel ridges or slits that disperses white light into its constituent wavelengths. Iridescence arising from diffraction gratings always takes the form of ... ordered spectra ... colours are ordered in the same sequence as the colours in the spectrum of visible light." https://lnkd.in/dRSiEq2 View in LinkedIn

COLORISTICS PAINTS. "The pigments are composed of organic polymers that rely on liquid crystal characteristics. These compounds retain liquid attributes while maintaining their crystalline integrity as a solid." https://lnkd.in/dUfM6fu View in LinkedIn

MODERN PIGMENTS. "In the 21st century, the new technology of synthetic pigments has opened up great possibilities in the realm of paints and pigments ... These special effect paints have high degrees of opalescence, iridescence, color shift, and angle-dependent color properties." https://lnkd.in/dUfM6fu View in LinkedIn

NEW NANO PIGMENTS. "Incorporation of synthetic flakes of bismuth and fish scales into automotive paints in the late 1950s led to some of the first synthetic special effect pigments incorporating pearlizing effects specifically."" "iridescence, color shift, and angle-dependent color properties." https://lnkd.in/dUfM6fu View in LinkedIn

STRUCTURAL COLOR MAKES IRIDESCENCE. "All structural color results from nanostructure, including in the iridescence tails of male peacocks ... the spacing between melanin rods varies to produce each discernable color. If we ground up a peacock tail feather, we would destroy the nanostructure and end up with a pile of fine, gray dust." https://lnkd.in/dFvtWWa View in LinkedIn

PIGMENTED COLOR. "In pigmented color, such as the red fur of a fox, red pigments in its coat absorb all colors except red. Our brain recognizes color when a specific wavelength, about 700 nanometers for red, reaches the light-sensitive cells in our retina and gets processed in the visual region of our brain." https://lnkd.in/dFvtWWa View in LinkedIn

NEW IRIDESCENT PAINTS. "Schenk set about finding pigments with similar reflective and color-changing qualities. She discovered that major advances had been made in color-shifting nanoparticles, but they were only produced for industrial uses, such as car finishes and cosmetics ... Schenk was able to adapt the industrial nanoparticles for artistic use." https://lnkd.in/dRdF4Z6 View in LinkedIn

BIOMIMICRY PAINT COMPANY. "Lifescaped, led by Professor Andrew Parker, is pioneering biomimetics: the science of learning from nature’s design principles. The team is trying to benefit from the trials and errors of 3.9 billion years of evolution."" " https://lnkd.in/dqVuX64 View in LinkedIn

CULTURED DIATOMS. "This would enable diatom shells to be mass-produced, harvested and mixed into paints, cosmetics and clothing to create stunning colour-changing effects, or embedded into polymers to produce difficult-to-forge holograms."
