Colours from living lands: A multi-sited ethnography of human-environment relationships in bio-based dyeing practices rethinks biocolours as an entanglement of practitioners, organisms, materials, and environments. Grounded in ecological anthropology and relational approaches to design, this work combines ethnography and practice-led research across Southern Finland, the Northwest Amazon, and Southern Japan. Through apprenticeship, walking, foraging, cultivating, and reflective making, it examines how colour emerges through embodied engagement and ecological rhythms. The study proposes a framework for future colour practices that encompasses embodied experiences, temporal variations, and adaptive practices. By situating colour within specific territories, the work advances a more relational and resilient approach to textile colour design.
