The Palacio do Planalto is the official workplace of the President of Brazil. It is located at the Praca dos Tres Poderes in Brasilia. As the seat of government, the term "Planalto" is often used as a metonym for the executive branch of government. The main working office of the President of the Republic is in the Palacio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palacio da Alvorada. Besides the President, senior advisors also have offices in the "Planalto," including the Vice-President of Brazil and the Chief of Staff. The other Ministries are along the Esplanada dos Ministerios. The architect of the Palacio do Planalto was Oscar Niemeyer, creator of most of the important buildings in Brasilia. The idea was to project an image of simplicity and modernity using fine lines and waves to compose the columns and exterior structures. The Palace is four stories high, and has an area of 36,000 m2. Four other adjacent buildings are also part of the complex.

Major League Baseball is especially well known for red teams. The Cincinnati Red Stockings are the oldest professional baseball team, dating back to 1869. The franchise soon relocated to Boston and is now the Atlanta Braves, but its name survives as the origin for both the Cincinnati Reds and Boston Red Sox. During the 1950s when red was strongly associated with communism, the modern Cincinnati team was known as the "Redlegs" and the term was used on baseball cards. After the red scare faded, the team was known as the "Reds" again. The Los Angeles Angels of Anaheim are also known for their color red, as are the St. Louis Cardinals, Arizona Diamondbacks, and the Philadelphia Phillies.
