摘要
In most situations in the real world, once an object is fabricated, the color is permanent and cannot be changed again. For the Emerging Technologies exhibit, we will present a technology to create re-programmable multi-color textures that are made from a single material only. This technology is based on photochromic dyes that can switch their appearance from transparent to colored when exposed to the light of a certain wavelength. By mixing cyan, magenta, and yellow (CMY) photochromic dyes into a single solution and leveraging the different absorption spectra of each dye, we can control each color channel in the solution separately. Our approach can transform single-material fabrication techniques, such as coating, into high-resolution multi-color processes. In addition, as the color-changing process is fully reversible, users can recolor objects multiple times.
