Harmony in Blue and Gold: The Peacock Room (better known as The Peacock Room) is a work of interior decorative art created by James McNeill Whistler and Thomas Jeckyll, translocated to the Freer Gallery of Art in Washington, D.C., which is part of the Smithsonian's National Museum of Asian Art. Whistler painted the paneled room in a unified palette of blue-greens with over-glazing and metallic gold leaf. Painted between 1876 and 1877, it now is considered one of the greatest surviving Aesthetic interiors, and best examples of the Anglo-Japanese style.
