Researchers from the Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Laboratory (CSAIL) developed a system that uses reprogrammable ink to allow objects to change colors when exposed to ultraviolet (UV) and visible light sources.

The PhotoChromeleon system uses a mixture of photochromic dyes that can be sprayed or painted onto the surface of any object; exposure to UV light saturates the colors in the dyes from transparent to full saturation, while exposure to white light desaturates them as desired.

Said MIT’s Stefanie Mueller, "By giving users the autonomy to individualize their items, countless resources could be preserved, and the opportunities to creatively change your favorite possessions are boundless."
