On Purple: The Purpose of Hue examines colour not merely as a visual phenomenon, but as a cultural, psychological, and symbolic language. Bringing together artists working across diverse disciplines, the publication explores how the colour purple has historically signified power, spirituality, transformation, ambiguity, and imagination. Through essays, curatorial reflections, and selected artworks, the catalogue investigates the ways colour shapes perception, emotion, and collective memory, revealing purple as a site where aesthetic experience intersects with cultural meaning.
