Chromoloop is a world-first that is the fruit of a research project by studio LoopLoop. It allows to colour aluminium using plant-based dyes, replacing standard petrol-based ones. The delicate patterns and colours that can be achieved are dictated by the plants that are used, contrasting with the robust materiality of aluminium. With the ambition to further explore questions of sustainable production and locality, the studio created its own dye garden consisting exclusively of plants species that are either native from- or naturalized in the Netherlands.
