Design a building façade in the manner of Richard Rogers where the external services are painted in a strict colour code so a passer-by can read the building — blue for air, green for water, yellow for electricity, red for movement and circulation. Compose a wall of exposed ductwork and pipe runs in saturated blue and green, bright yellow cable trays, a red external escalator tube climbing diagonally across the elevation, white structural steel behind, the code applied consistently with no decorative colour, clear daylight, oblique eye-level view, 24mm lens, architectural photography, ultra photorealistic, 8K
