(Phys.org)—Researchers are developing a technology that could one day make paint and color packaging labels that never fade. The color is produced by a type of nanostructure called a "plasmonic pixel." These pixels are made of aluminum nanoantennas, and when the free electrons in the metal collectively vibrate at specific frequencies, they produce a specific color.
