Spectrum is a conceptual light installation developed as an Expression of Interest (EOI) for Vivid Sydney, exploring the relationship between light, colour and the symbolism of new beginnings.

Inspired by the natural phenomenon of a rainbow appearing after a storm, the proposal uses a single source of white light projected through a series of prisms, separating it into a spectrum of colours across the surrounding surfaces.

Conceived for the undercroft of Sydney's Cahill Expressway, the installation transforms a simple optical phenomenon into an immersive spatial experience, allowing visitors to encounter the changing colours of light at an architectural scale.

Beyond its visual qualities, Spectrum explores light as a metaphor for diversity, connection and hope. While white light represents a shared origin, the colours revealed through the prisms symbolise the individuality and diversity of people within a community.

Through the interaction between light, material and space, the proposal imagines a temporary public installation celebrating the possibility of a brighter and more colourful future.
