Color Shifting Paints
The ColorShiftTM effect created by ChromaFlair® pigments is the result of a phenomenon that occurs when light hits an ultra-thin, multi-layer interference flake. This flake is opaque and reflects the light back to the eye, just like a mirror. The shift in color is created by the variances in light interference through layers of the flake. Flex Products Inc. calls this unique color generation technology Color by Physics®.
The key to these paints are synthesized flakes that are one micron thick—or about 1/50th the thickness of a human hair. Each flake is made up of several layers, laid on symmetrically. At the center is an opaque, mirrorlike aluminum core covered on both sides by a layer of glasslike magnesium fluoride.
Finally, over each glass layer is an ultra-thin, semi-transparent layer of chrome. Production tolerances are so tight they’re measured in atoms. Light passes into each flake through the two outer layers and reflects off the aluminum core, being refracted by the glasslike layer. In fact, it’s the thickness of this layer that determines the color range you’ll see in a given pigment. Because the flakes are symmetrical, it doesn’t matter which side is facing outward. Plus, even on the microscopic scale, they’re much smoother than conventional metallic flakes, so they provide better reflectivity and more saturated colors.
Flex Products makes eight different
pigments, each representing a different color range (red/gold,
cyan/purple, silver/green, and so on).
Perhaps even more amazing than the
elusively shifting colors, though, is that the materials used in the ChromaFlair
pigments that give these paint lines their magic are completely colorless. The
bright colors we see are solely from light refracting off the paint, a
phenomenon similar to seeing rainbows in soap bubbles or oil slicks
One of the nice things about this paint is that, because the ChromaFlair pigment contains no organic materials, their color effect won’t fade over time. Should spot repainting be necessary due to bodywork, color matching is easy, since there’s no variation in the eight basic types of flakes.
