# Freshness Revealing Packages Ko Yang Warns of Expiry With Changing Colors By Jessica Marcel | Published 2010-01-25 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/ko-yang References: [cribcandy](http://cribcandy.com/home/picks/color-changing-milk-boxes/39668/) & [inewidea](http://www.inewidea.com/2010/01/20/18596.html#more-18596) Artist Ko Yang designed this [milk carton](https://www.trendhunter.com/trends/expiremate) to [change colors over time](https://www.trendhunter.com/trends/colorchanging-cold-cups). That way, if it’s old, it should reveal its non-freshness without a sniff test. The box changes from all white to all cheese. Cheese, in this case, is a color represented by some kind of nasty looking orange splotches. If it looks like cheese, you probably shouldn’t drink it. Ko Yang has a good idea here for consumers, although sellers might not be so quick to jump at this idea. ## Trend Insights (Trend Hunter) - Score: 2.9/10 - Popularity: 28% | Activity: 52% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Health](https://www.trendhunter.com/health) ## Key Themes ### What Makes This Trend Stand Out - **Freshness Detection Packaging:** Artificial Intelligence-powered freshness detection technology in packaging can help consumers and sellers know the expiry dates of the products without opening the package. - **Smart Color-changing Packaging:** Packaging that changes color over time can alert consumers to the freshness of the product and encourage them to consume it within the recommended time period. - **Sustainability-oriented Packaging:** Sustainable packaging materials and designs that extend the shelf life of goods can reduce food waste and support environmentally-conscious consumers. ### Sectors Adopting This - **Food and Beverage:** The food and beverage industry can benefit from the adoption of freshness detection packaging to reduce spoilage and enhance customer experience. - **Retail:** Retailers can leverage smart color-changing packaging to differentiate their products and attract customers who value freshness and quality. - **Packaging and Labeling:** The packaging and labeling industry can explore sustainable and cost-effective designs that improve the shelf life of goods and reduce environmental impact. ## Related on Trend Hunter - [Freshness-Tracking Food Containers](https://www.trendhunter.com/trends/vorkoster-lid.md) - [Color-Changing Beer Labels](https://www.trendhunter.com/trends/coors-bottles.md) - [Temperature-Sensitive Mayo Jars](https://www.trendhunter.com/trends/hellmanns-smart-jar.md) - [Thermochromic Ink Packaging](https://www.trendhunter.com/trends/thermochromic-ink.md) - [Biodegradable Cheese Packagings](https://www.trendhunter.com/trends/selfpacking-cheese.md) - [Food Waste-Combatting Smart Stickers](https://www.trendhunter.com/trends/grey-colombia.md) - [Anti-Waste Dairy Branding](https://www.trendhunter.com/trends/coop-milk-branding.md) - [Expiration Date Elimination Initiatives](https://www.trendhunter.com/trends/morrisons.md) - [Adorable Cat Milk Cartons](https://www.trendhunter.com/trends/adorable-blue-cat.md)
