The extensive use of synthetic pigments and dyes in art and design presents environmental and health challenges, creating an urgent need for sustainable alternatives that meet aesthetic, functional, and economic requirements. Structural Colour: Beyond Pigment addresses this topic through an interdisciplinary research project at KASK Biolab, built on top of a previous practice-based research and expertise in colour – blending art, design, science and technology.

In nature, colour comes from pigments (pigmented colouration) and structures (structural colouration) made from abundant, biodegradable and non-toxic biobricks that interfere with light. Inspired by natural phenomena such as iridescence, the project focuses entirely on the creation of these structures using natural elements as construction materials and their potential as an innovative alternative to pigments in art and design, questioning how artistic methodologies can contribute to new insights into material research.

Using a design through making approach, the project develops sustainable protocols for producing structural colours from three natural biobricks — melanin, cellulose, and silica — combined with natureinspired structures such as thin films, diffraction gratings, and photonic crystals. Laboratory protocols for structural colour production and a physical and digital material database will be created to share our knowledge. Intensive collaborations with professionals and students, combined with laboratoryinitiated artistic projects, will explore the significance and potential of structural colours in contemporary art and design practice.
