T H E U N S E E N Choropleth

Launching on Earth Day 2018, Somerset House will raise a flag which reflects the impact of pollution on the environment around Somerset House. 

Created by T H E U N S E E N, a material craft and innovation studio which started life at Somerset House, the Choropleth flag uses a chromic colour change compound developed by T H E U N S E E N, which reacts in real-time to ultraviolet (UV) radiation. This compound has been applied to a tote bag and t-shirt, which are available exclusively through the Somerset House Shop.
