The architect specialized in lighting design is responsible for the special lighting of the facades of the buildings occupied by the exhibition, as well as the gardens, walkways, and artistic installations that permeate the circuit. "The route inspires the observation of the marks left by the passage of time," he comments. Hence the emphasis on the bright yellow paint and the subtle reliefs and bas-reliefs of the facades. With an eye on sustainability and respect for the local fauna, low-consumption LEDs were chosen, warm colors, and a high color rendering index (CRI) - above 90%.
