Luxury Dark Marble Kitchen Background

Create a luxury, non-distracting background image suitable for a premium product infographic. Scene: a high-end modern kitchen or surface featuring dark marble or charcoal stone with subtle, natural veining. Colour palette must be muted and elegant: deep charcoal, soft black, warm grey, stone, and subtle taupe tones. Avoid bright whites, strong patterns, or saturated colours. Lighting should be soft, diffused, and warm, creating a refined, upscale atmosphere without harsh highlights or shadows. The background must be slightly out of focus with low visual contrast, designed to sit behind text, icons, and a wooden product without competing for attention. No people, no hands, no food, no props, no clutter. No strong highlights, no reflections, no high-contrast edges. The image should feel premium, calm, and timeless, similar to luxury homeware or kitchen brand photography. Designed specifically as a background layer for an infographic, where clarity and readability are the priority.
