London-based material design studio, The Unseen, has always experimented with the infusion of color changing technology, dabbling with [color-changing hair dye](https://www.trendhunter.com/trends/phreeze) and [hypercolor fashion pieces](https://www.trendhunter.com/trends/programmable-clothing). The color-obsessed designers at The Unseen collaborated with British life style company, the [Lost Explorer](https://www.trendhunter.com/trends/brewdog-planet-pale), 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. ## Trend Insights (Trend Hunter) - Score: 4.2/10 - Popularity: 52% | Activity: 66% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Pollution-reacting Textiles:** Opportunity for textile companies to develop pollution-reacting materials for various apparel. - **Color-changing Technology:** Innovative products can be developed using color-changing technology such as hair dye and fashion pieces. - **Environmental Sustainability Fashion:** Fashion companies can focus on producing sustainable products that create awareness about environmental issues. ### Where This Applies - **Textile Industry:** Textile companies can collaborate with environmentalists to produce sustainable clothing using pollution-reacting materials. - **Consumer Goods Industry:** Consumer goods companies can explore color-changing technology to create innovative and eco-friendly products. - **Fashion Industry:** Fashion companies can take up the responsibility to create environmental awareness and sustainable products to customers. ## Related on Trend Hunter - [Adaptable Anti-Odor T-Shirts](https://www.trendhunter.com/trends/wellen-patinatech-tshirt.md) - [Tree-Planting T-Shirt Lines](https://www.trendhunter.com/trends/treedom.md) - [Hydrophobic Technical Tees](https://www.trendhunter.com/trends/technical-tee.md) - [Organic Water Quality Testers](https://www.trendhunter.com/trends/colores-del-rio.md) - [Pollution-Removing Murals](https://www.trendhunter.com/trends/this-campaign-sucks.md) - [Biomaterial Color-Changing Installations](https://www.trendhunter.com/trends/sensibiom-2.md) - [Eco-Friendly Fashion Color Dyes](https://www.trendhunter.com/trends/cone-denim-1.md) - [Touch-Activated Color-Changing Chairs](https://www.trendhunter.com/trends/pangolin.md) - [Sustainably Inked Whisky Bottles](https://www.trendhunter.com/trends/johnnie-walker-bottles.md)
