<https://s.mj.run/CAgGZ52O-j4> Generate four elegant, minimalist variations of the ceiling design featuring aluminum tubes with a wood-look finish. Each variation should use a different wood tone, from light oak to deep walnut, capturing a range of natural wood colors to complement the refined style. The aluminum tubes should retain their smooth, tubular form, with realistic grain patterns that vary subtly across the tones. Ensure the wood-like finish appears high-quality and sophisticated, emphasizing warmth and texture without losing the sleek metallic nature of the material. The overall design should feel modern and upscale, suitable for luxurious interior spaces. --s 750
