The rediscovery of natural dyes today necessitates delving into past histories in order to rediscover recipes, processes and best practices. As well, scientific knowledge is key to producing new practices adapted to today’s demands, including moving from small-scale applications to reliable large-scale ones with industry impact. Learning and knowing about natural dyes thus necessitates an interdisciplinary approach and encompasses not only learning about how to make natural dyes but also teaching the public why natural dyes are crucial today.
