This collaboration was not just about developing a new material but about shifting perspectives, rethinking colour beyond the standardised, industrial palette towards something dynamic, renewable, and uniquely expressive. Could bacteria-based pigments one day redefine automotive coatings? The journey has only just begun.
Bacteria-based pigments offer a radical departure from traditional colourants. Instead of synthetic or mineral-based pigments, these colours emerge through a natural fermentation process, where bacteria metabolise nutrients into striking hues. Depending on the bacterial strain, the pigments can be harvested and refined for uniform application, or cultivated directly on a substrate, creating organic, one-of-a-kind patterns.
While bacteria-based pigments hold great potential, they also present challenges. The automotive industry requires coatings that meet rigorous durability and performance standards, and as this is still an emerging field, much research is needed to bring such bio-based colours to market. However, projects like this help set change in motion, opening new dialogues between science, industry, and design.
