Design a sleek, modern interior scene for a website background, featuring a sophisticated palette of grey, graphite, white, and deep navy blue tones. The space should have light grey walls, dark graphite accents on furniture or cabinets, and touches of white in details like lamps, shelving, or decorative items. Incorporate deep navy blue in key elements like cushions, artwork, or curtains. The overall composition should be minimalist, with clean lines and subtle color transitions, allowing for a polished yet cozy look, ideal for a professional, stylish website backdrop."
