A sleek and professional modern website design mockup for an exclusive art community, featuring a luxurious deep navy background (#2C3E50) accented with gold highlights (#D4AF37) for a sense of authority and sophistication. Use clean white sections (#FFFFFF) for content areas and pastel blue highlights (#AEDFF7) for user-friendly buttons and navigation. Incorporate soft gray tones (#BDC3C7) for secondary text and subtle borders. Add a striking deep red (#C0392B) call-to-action button for emphasis, complemented by green accents (#27AE60) in small details to symbolize growth and connection. The layout is minimalistic, with a prominent header, grid-style sections for featured artists, and a sidebar for user interaction. Include a balance of light and dark areas for contrast and readability. --ar 16:9
