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

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

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

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

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

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

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

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

SYNTHETIC IRIDOPHORE NANOPARTICLES. "The particle size can be tuned with salts that control the interactions between charges on the proteins." (Tuning is equivalent to doping of semiconductors). https://lnkd.in/dMaBF7b View in LinkedIn
