Blue Room, Formal reception room in the White House.
The Blue Room is one of three state parlors on the first floor in the White House, the residence of the President of the United States.
It has been traditionally decorated in shades of blue since 1837.
The Blue Room is used for receptions and receiving lines, and is occasionally set for small dinners.
President Grover Cleveland married Frances Folsom in the room on June 2, 1886, the only wedding of a President and First Lady in the White House.
The round shape of the room measures approximately 30 feet in diameter.
