Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues at KU-KIST in Seoul have developed a new approach that overcomes this limitation, producing bright, stable colors spanning the full visible spectrum. The research has been published in Proceedings of the National Academy of Sciences.
