Material studio THE UNSEEN has developed a form of ink that reacts with fluctuations in the air to change color. On the one hand, it's basically like a mood ring, but fabric. On the other hand, we're talking about clothes that will suddenly shift colors in a stiff breeze. Which is awesome.
Artist Lauren Bowker and THE UNSEEN used fabric treated with the ink in a capsule collection for Swarovski entitled Air, which debuted during London's Fashion Week 2014.
Here's a description of how it works from My Modern Met:
The biological and chemical technology is integrated into layers of fabric and transforms its color in response to pressure change. Air's nano compounds, inks, and dyes are capable of sensing up to seven stimuli: heat, UV, pollution, moisture, chemicals, friction, and sound. Each element has a different color-altering effect; pollution, for instance, can change between yellow to black. The result is that it translates our environment into a stunning visual representation, where a multi-faceted garment is reminiscent of an insect's iridescent exoskeleton.
