Harmony in Blue and Gold: The Peacock Room (better known as The Peacock Room) is a masterpiece of interior decorative art created by James McNeill Whistler and Thomas Jeckyll, translocated to the Freer Gallery of Art in Washington, DC. Whistler painted the paneled 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.
