Library Atrium with Grille Light Transmission: Purple Walls and Square Skylights

Design a library atrium in the manner of Ricardo Legorreta where a tall shaft rises through the building, its walls painted in flat planes of purple, yellow and terracotta and lit only from square skylights at the top. Compose the coloured planes stepping back as they rise, one long stair crossing the void, a hanging kinetic sculpture of coloured discs, plain polished concrete floor, cool interior shade with intense coloured bounce light, low view straight up the shaft, 24mm lens, interior photography, ultra photorealistic, 8K
