Water, an important resource, is limited. Current dyeing processes in the fashion industry are focused on highly polluting dyes. Interdisciplinary collaboration between design and natural science has resulted in innovative microalgae inks for printing on textiles. The aim is to sensitise the viewer to the temporary and sustainable nature of clothing, as the prints dissolve when they come into contact with light. It is up to the wearer to decide how to deal with the "living" microalgae prints. In this way, organic processes and their temporary nature are elevated to the level of aesthetics.
