The Peacock Room

Harmony in Blue and Gold: The Peacock Room (better known as The Peacock Room) is James McNeill Whistler's masterpiece of interior decorative mural art. He painted the panelled room in a rich and unified palette of brilliant blue-greens with over-glazing and metallic gold leaf. Painted between 1876–77, it now is considered one of the greatest surviving aesthetic interiors, and best examples of the Anglo-Japanese style.
