These pollution-reacting t-Shirts will change color in the wash based on your city's pollution levels. London-based material design studio, The Unseen, has always experimented with the infusion of color changing technology, dabbling with color-changing hair dye and hypercolor fashion pieces.
The color-obsessed designers at The Unseen collaborated with British life style company, the Lost Explorer, to develop shirts that will look differently in Toronto, than they do in New York. The shirts are made with cabbage juice, a natural pH indicator that will turn red, pink, or magenta in acids and blue and yellow in alkaline solutions. The colors of the t-shirts range on a scale of dark purple, to royal blues, and faded pastels.
These pollution-reacting t-shirts stand as a reminder of the important role fashion can take with regards to important issues like environmental sustainability.
