SYNTHETIC IRIDOPHORE NANOPARTICLES. "His team has inserted the gene that encodes a reflectin protein in the longfin inshore squid Loligo pealeii into Escherichia coli bacteria. When expressed, the protein collapses into nanoparticles." https://lnkd.in/dMaBF7b View in LinkedIn

BIOMIMICRY. "Professor Andrew Parker has grown cells from butterfly wings and weevil shells in his lab at the museum, bringing scientists a step closer to creating shimmering colours which never fade. "These shimmering colours are not caused by pigments or dyes but materials with a nano-structure." https://lnkd.in/dWW45k6 View in LinkedIn

INTERFERENCE PAINTS "do give tonal shifts when layered over different base colors ... interference pigments exhibit the most obvious color properties when glazed over a dark background. Golden Acrylics has a variation in their interference acrylics that allows for the addition of a texturizing additive that gives higher dimension to the paint." https://lnkd.in/dUfM6fu View in LinkedIn

REVERSIBLE COLORS. "In a few species of beetles, reversible colour change is effected by partially hydrating or dehydrating multilayer structures, thus changing the refractive index of porous layers; this mechanism is also known as ‘hygrochromic colour’." https://lnkd.in/dRSiEq2 View in LinkedIn

COLORISTICS PAINTS. "This technology allows for increased manipulation of the molecules in their orientation and therefore similar deposit systems can be achieved for color-shift effects. The crystals are aligned much like vertical cigars and the color shift varies with the angle of pitch to the horizontal of packed structures." https://lnkd.in/dUfM6fu View in LinkedIn

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
