Color Changing Clothes Could Match Mood, Surroundings

Next-generation threads may soon give a whole new meaning to the phrase “change your clothes”—advanced new fibers that can change color with a flip of a switch.

The threads may one day be used to make clothing that suits the wearer’s mood or to allow a person to blend in with the environment.

The concept is similar to the way light-sensitive eyeglass lenses darken when exposed to sunlight.
