What color is Washington wearing in The Apotheosis of Washington?

In "The Apotheosis of Washington," the central figure, George Washington, is depicted wearing a robe that is predominantly purple. This choice of color is significant, as purple has long been associated with royalty, power, and nobility. It symbolizes Washington's status as a revered leader and his god-like elevation in the art, which celebrates his contributions to the founding of the nation.

Additionally, the artwork itself is located in the dome of the U.S. Capitol, reflecting its importance in American history and culture. The use of purple not only enhances the visual impact of Washington's figure in the fresco but also serves to reinforce the idea of his elevated legacy. This choice aligns seamlessly with the themes of honor and reverence intended by the artist, Constantino Brumidi, as he crafted this monumental piece. The other color options do not embody these associations in the same way, which is why purple stands out as the correct answer.
