Vivienne works not only with traditional Japanese black ink | sumi-e, but also with soil pigments collected from around the world, organic pigment sticks crafted in Japan, and finely ground minerals. Each material is carefully sourced with an emphasis on sustainability — drawn from the earth and able to return to it without leaving a trace of pollution. Her practice reflects a deep commitment to natural cycles, incorporating raw elements into her art while honouring their origins and their ability to reintegrate with the environment.
