Fabulous Fungi creates sustainable textile dye made from fungi. Unlike synthetic dyes, this innovation relies on natural processes that require no harmful chemicals, use significantly less water, and cause no water pollution. During the Wereldhavendagen, Fabulous Fungi explored how visitors perceive their color palette (including the shade Clean Coral), the natural fading of the dye, and their willingness to pay more for sustainably dyed clothing. This was studied through a tear-off card survey, a statement board, and interviews with visitors.
