Design a vibrant playroom in Art Nouveau style, inspired by the works of Alphonse Mucha and Gustav Klimt, with a color palette of rich emerald green, golden yellow, and deep crimson. The space features a soaring ceiling adorned with organic, flowing metalwork and intricate floral patterns. Walls are painted a soft, creamy white, while floors are made of rich, dark hardwood. A plush, oversized sectional sofa in emerald green velvet is nestled against a floor-to-ceiling bookshelf lined with leather-bound volumes and vintage poster art. A beautiful, hand-carved wooden armoire in golden yellow finishes serves as a toy storage unit, while a stunning, Art Nouveau-inspired chandelier hangs from the ceiling, casting a warm, golden glow over the space.
