New multicolor 3D printing technology is inspired by chameleons, says study

Researchers at the University of Illinois Urbana-Champaign have developed a sustainable approach for 3D-printing dynamic colors from a single ink, inspired by chameleons' color-changing abilities. By modulating structural color using UV-assisted direct-ink-write 3D printing, they can create color gradients in the visible wavelength spectrum without the need for multiple paints.
